RESUMEN

BACKGROUND: Approximately 1 in 4 athletes returning to sports will sustain a second anterior cruciate ligament (ACL) injury. Psychological factors related to kinesiophobia, confidence, and psychological readiness are associated with second ACL injury; however, the evidence is conflicting. HYPOTHESIS: Athletes who sustain a second ACL injury (ie, graft rupture or contralateral ACL rupture) within 2 years of ACL reconstruction (ACLR) would have greater kinesiophobia, less confidence, and lower psychological readiness prior to return to sport (RTS) compared with athletes who do not sustain a second ACL injury. STUDY DESIGN: Secondary analysis of a prospective randomized trial. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 39 female Level I/II athletes completed the following measures after postoperative rehabilitation and a 10-session RTS and second ACL injury prevention program: ACL Return to Sport after Injury (ACL-RSI) scale, the 11-item Tampa Scale of Kinesiophobia (TSK-11), and question 3 on the Knee injury and Osteoarthritis Outcome Score (KOOS) quality of life (QoL) subscale. Athletes were dichotomized based on whether they sustained a second ACL injury within 2 years of ACLR or not. Independent t tests determined group differences in TSK-11, KOOS-QoL, ACL-RSI, and the 3 individual components of the ACL-RSI (ie, emotions, confidence, risk appraisal). RESULTS: Nine athletes sustained a second ACL injury (4 graft ruptures and 5 contralateral ACL ruptures). The group that sustained a second ACL injury had higher scores on the ACL-RSI (P = 0.03), higher on the risk appraisal questions of the ACL-RSI (P < 0.01), and met RTS criteria sooner than athletes who did not (P = 0.04). All second ACL injuries occurred in athletes who underwent primary ACLR with hamstring tendon autografts. CONCLUSION: Athletes who sustained a second ACL within 2 years of ACLR had a more positive psychological outlook, higher scores on the specific questions related to the risk appraisal construct of the ACL-RSI, and met RTS criteria sooner than athletes who did not sustain a second ACL injury. CLINICAL RELEVANCE: Counseling athletes about delaying RTS to reduce the risk of second ACL injury may be especially important in athletes who display high psychological readiness and meet RTS criteria sooner.

RESUMEN

BACKGROUND: Psychological readiness to return to sport has emerged as an important factor associated with outcomes after anterior cruciate ligament reconstruction (ACLR). Psychological factors are potentially modifiable during the course of rehabilitation, and improving them may lead to better outcomes. PURPOSE: To determine whether athletes with a positive psychological response after participation in a neuromuscular training and second injury prevention program had better self-reported function and activity outcomes compared with athletes who did not have a meaningful change. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: After ACLR and the completion of formal rehabilitation, 66 level I/II athletes completed the following self-reported measures at enrollment (pretraining): the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale, the International Knee Documentation Committee (IKDC) subjective knee form, and the 5 subscales of the Knee injury and Osteoarthritis Outcome Score (KOOS). Participants completed these measures after 10 sessions of agility, plyometric, and progressive strength training and at 1 and 2 years after ACLR. Participants who displayed an increase in the ACL-RSI score from pretraining to posttraining that exceeded the minimal clinically important difference (≥10 points) were defined as having a positive psychological response (responders) to training, and those who did not were defined as nonresponders. A mixed-model analysis of variance was used to determine if group differences in IKDC and KOOS scores existed over the 4 time points (pretraining, posttraining, and the 1- and 2-year follow-ups). RESULTS: The responders reported better self-reported function compared with the nonresponders, regardless of time, on the IKDC form (P = .001), KOOS-Sport and Recreation (P = .014), KOOS-Pain (P = .007), and KOOS-Symptoms (P = .002) but not on the KOOS-Quality of Life (P = .078). Overall, 77% of responders and 67% of nonresponders returned to their previous level of sport by 1 year after ACLR (P = .358), and 82% of responders and 78% of nonresponders returned to their previous level of sport by 2 years after ACLR (P = .668). CONCLUSION: Ultimately, 59% of the athletes in this study displayed a meaningful improvement in their psychological outlook over the course of the training program. Responders demonstrated persistently better self-reported function at posttraining and at 1 and 2 years after ACLR, but there were no between-group differences in return-to-sport rates.

RESUMEN

OBJECTIVE: To determine whether the addition of perturbation training to a secondary injury prevention program reduces the rate of second anterior cruciate ligament (ACL) injury compared to the prevention program alone. DESIGN: Single-blinded randomized controlled trial. METHODS: Thirty-nine female athletes who intended to return to cutting/pivoting sports were enrolled 3 to 9 months after primary anterior cruciate ligament reconstruction (ACLR). Athletes were randomized to receive a training program of either progressive strengthening, agility, plyometrics, and prevention (SAPP) (n = 20) or SAPP plus perturbation training (n = 19); each had 10 sessions over 5 weeks. Occurrence and side of second ACL injury were recorded for 2 years after primary ACLR. RESULTS: There were 9 second ACL injuries in the 2 years after ACLR. There was no statistically significant difference in rate or side of second ACL injury between the SAPP-plus-perturbation training and SAPP groups. CONCLUSION: Adding perturbation training to a secondary ACL injury prevention program did not affect the rate of second ACL injury in female athletes. J Orthop Sports Phys Ther 2020;50(9):523-530.

RESUMEN

BACKGROUND: Outcomes after anterior cruciate ligament reconstruction (ACLR) are not uniformly good and are worse among young female athletes. Developing better rehabilitation and return-to-sport training programs and evaluating their outcomes are essential. PURPOSE: (1) Test the effect of strength, agility, plyometric, and secondary prevention (SAPP) exercises with and without perturbation training (SAPP + PERT) on strength, hops, function, activity levels, and return-to-sport rates in young female athletes 1 and 2 years after ACLR and (2) compare 2-year functional outcomes and activity levels among young female athletes in the Anterior Cruciate Ligament Specialized Post-Operative Return-to-Sports (ACL-SPORTS) trial to homogeneous cohorts who completed criterion-based postoperative rehabilitation alone (Multicenter Orthopaedic Outcomes Network [MOON]) and in combination with extended preoperative rehabilitation (Delaware-Oslo). STUDY DESIGN: Randomized controlled trial, Level of evidence, 1; and cohort study, Level of evidence, 3. METHODS: A total of 40 level 1 and level 2 female athletes were enrolled after postoperative impairment resolution 3 to 9 months after primary ACLR. Participants were randomized to 10 SAPP or SAPP + PERT sessions and were tested 1 and 2 years after ACLR on quadriceps strength, hop tests, functional outcomes, and return-to-sport rates. Participants were then compared with homogeneous cohorts of young (<25 years) female athletes who completed criterion-based postoperative rehabilitation alone (MOON) and in combination with extended preoperative rehabilitation (Delaware-Oslo) on 2-year functional outcomes. RESULTS: No significant or meaningful differences were found between SAPP and SAPP + PERT, so groups were collapsed for comparison with the other cohorts. At 2-year follow-up, ACL-SPORTS had the highest scores (P < .01) on the Marx activity rating scale (ACL-SPORTS, 13.5 ± 3.3; Delaware-Oslo, 12.5 ± 2.7; MOON, 10.6 ± 5.1); International Knee Documentation Committee Subjective Knee Evaluation Form (96 ± 7, 92 ± 9, and 84 ± 14, respectively); and Knee injury and Osteoarthritis Outcome Score (KOOS) subscales for Pain (98 ± 4, 94 ± 9, and 90 ± 10, respectively), Symptoms (94 ± 6, 90 ± 9, and 83 ± 14, respectively), Activities of Daily Living (100 ± 1, 99 ± 4, and 96 ± 7, respectively), Sports and Recreation (94 ± 8, 86 ± 15, and 82 ± 17, respectively), and Quality of Life (89 ± 14, 78 ± 18, and 76 ± 19, respectively). The Patient Acceptable Symptom State threshold on the KOOS-Sports and Recreation was achieved by 100% of the ACL-SPORTS cohort compared with 90% of Delaware-Oslo and 78% of MOON (P = .011). CONCLUSION: Although perturbation training provided no added benefit, 10 sessions of return-to-sport training, compared with criterion-based postoperative rehabilitation alone, yielded statistically significant and clinically meaningfully higher 2-year functional outcomes among young, high-level female athletes after ACLR. REGISTRATION: NCT01773317 (ClinicalTrials.gov identifier).

RESUMEN

Self-compassion involves extending kindness and understanding to one's self. Research has demonstrated inverse relationships between self-compassion and maladaptive constructs associated with obsessive-compulsive disorder (OCD), including emotion regulation (ER) difficulties. The current study sought to explore associations between self-compassion, ER difficulties, and OCD severity. Data were collected at the International Obsessive-Compulsive Disorder Foundation convention from 62 attendees who reported having a diagnosis of OCD (51% male, mean age 35.9 years). Findings demonstrated that self-compassion and ER difficulties were associated with overall OCD severity. Results also indicated that ER difficulties mediated relationships between self-compassion and overall OCD severity, as well as the severity of two OCD symptom dimensions, responsibility for harm and unacceptable thoughts. These findings suggest that self-compassion and ER difficulties may be involved in the maintenance and severity of OCD.

RESUMEN

BACKGROUND: The Anterior Cruciate Ligament-Specialized Post-Operative Return to Sports (ACL-SPORTS) randomized control trial (RCT) examined an evidence-based secondary ACL injury prevention training program, involving progressive strengthening, agility training, and plyometrics. The RCT examined the benefit of the training program with and without a neuromuscular training technique called perturbation training. HYPOTHESIS/PURPOSE: The purpose of this study was to report the return to sport and second ACL injury incidence outcomes of the men in the ACL-SPORTS trial. STUDY DESIGN: Secondary analysis of a RCT. METHODS: Forty cutting and pivoting sport male athletes participated in the ACL-SPORTS trial, return to sport testing, and in follow-up sessions at one and two years after ACL reconstruction. Variables of interest at one and two years were return to sport, return to preinjury level of sport, and second ACL injuries. Mean time to passing return to sport criteria, the number of athletes returning to sport and preinjury level of sport and the incidence proportion of second ACL injuries were calculated. RESULTS: Athletes passed return to sport criteria 232 ± 99 days after ACLR. One year after ACL reconstruction 95% had returned to sport, 78% at their preinjury level. Two years after ACL reconstruction all athletes had returned to sport, 95% at their preinjury level and only one athlete had a second ACL injury. CONCLUSIONS: The results of this study indicate that men in the ACL-SPORTS trial had much higher return to sport rates and much lower second ACL injury rates than those reported in the literature. LEVEL OF EVIDENCE: 1b.

RESUMEN

OBJECTIVE: To perform a systematic review and meta-analysis identifying (1) potential modifiable risk factors and (2) associated modifiable factors for patellar tendinopathy in athletes. DESIGN: A systematic review and meta-analysis was conducted. Risk of bias was assessed using the Newcastle-Ottawa Scale and grouped based on study design. Meta-analytic statistics were performed for items reported by five or more studies. A strength of evidence rating is provided for items not appropriate for meta-analysis. DATA SOURCES: PubMed, Web of Science, Scopus and Cinahl were searched on 14 November 2017. ELIGIBILITY CRITERIA: Quantitative, original research reporting potential modifiable risk factors or associated factors, comparing athletes with patellar tendinopathy with a group without the injury. RESULTS: 862 records were screened and 31 articles were included (6 prospective, 25 cross-sectional). There was a lack of strong evidence for any potential modifiable risk factor or associated factors. There was limited or conflicting evidence that decreased ankle dorsiflexion range of motion, decreased posterior thigh and quadriceps flexibility, greater volume of jump training, more volleyball sets played per week, greater countermovement jump (CMJ) height and greater activity volume are potential modifiable risk factors. Meta-analysis supported greater activity volume (Cohen's d=0.22, 95% CI 0.06 to 0.39, p=0.008), higher body weight (0.36, 0.17 to 0.55, p<0.001) and greater CMJ height (0.31, 0.07 to 0.56, p=0.01) as associated modifiable factors. CONCLUSIONS: There is a lack of strong evidence for any potential modifiable risk factors or associated factors. Factors with lower levels of support may be of interest in designing prevention programmes but require further research in high-quality, prospective studies.

RESUMEN

BACKGROUND: Norton and Robinson [2010. Development and evaluation of the anxiety disorder diagnostic questionnaire. Cognitive Behaviour Therapy, 39(2), 137-149. doi: 10.1080/16506070903140430 ] developed the Anxiety Disorder Diagnostic Questionnaire (ADDQ) as a transdiagnostic assessment of fear and anxiety to address problems in using diagnosis-specific measures as well as limitations with the extant transdiagnostic measures of anxiety. The present study validated a weekly version of the ADDQ, the Anxiety Disorder Diagnostic Questionnaire - Weekly (ADDQ-W) allowing session-by-session transdiagnostic assessment of anxiety. METHOD: Data were a secondary analysis of 49 treatment-seeking outpatient adults from a previous clinical trial. The ADDQ-W was administered weekly over the course of 12-group therapy sessions. RESULTS: The ADDQ-W was a valid weekly measure and neither scores, F(2, 37) = 2.70, p = .08, nor trajectories of change, F(2, 37) = 0.31, p = .73, differed by primary diagnosis, though power was limited. Rate of ADDQ-W change was predictive of change in both primary diagnosis severity, t = 2.40, p = .02, ß = 0.32, and overall severity, t = 3.01, p < .01, ß = 0.36, at post-treatment. CONCLUSIONS: This study has established initial support for the use of the brief, easily scored, ADDQ-W for repeated assessment over treatment using a diagnostically heterogeneous clinical sample of treatment-seeking individuals.

RESUMEN

Limited work has examined worry, or apprehensive anticipation about future negative events, in terms of smoking. One potential explanatory factor is the tendency to respond inflexibly and with avoidance in the presence of smoking-related distress (smoking-specific experiential avoidance). Participants (n = 465) were treatment-seeking daily smokers. Cross-sectional (pre-treatment) self-report data were utilized to assess trait worry, smoking-specific experiential avoidance, and four smoking criterion variables: nicotine dependence, motivational aspects of quitting, perceived barriers to smoking cessation, and severity of problematic symptoms reported in past quit attempts. Trait worry was significantly associated with greater levels of nicotine dependence, motivation to quit smoking, perceived barriers for smoking cessation, and more severe problems while quitting in the past; associations occurred indirectly through higher levels of smoking-specific experiential avoidance. Findings provide initial support for the potential role of smoking-specific experiential avoidance in explaining the association between trait worry and a variety of smoking processes.

RESUMEN

OBJECTIVE: This study examined the effect of a single session motivational interviewing (MI) intervention on engagement in a 12-week transdiagnostic group cognitive behavioral therapy (CBT) treatment for anxiety. METHOD: Participants were randomized to MI (N = 20) or non-MI (N = 19) conditions before enrolling in a 12-week group CBT program. Participants in the MI condition received an individual 50-minute MI session adapted from the longer MI pretreatment protocol, developed by Westra and Dozois () and Westra (). RESULTS: Rates of treatment initiation and treatment expectancies were significantly higher among participants who received the MI pretreatment intervention. Results indicate substantial reduction in clinician-rated anxiety severity after transdiagnostic group CBT, with no significant differences between MI and non-MI conditions. CONCLUSION: These findings suggest that a single MI pretreatment session may have positive effects on proximal measures of treatment engagement, but that these effects may not affect the severity of anxiety symptoms over the course of CBT.

RESUMEN

Sexual obsessions are a common symptom of obsessive-compulsive disorder (OCD), often classified in a broader symptom dimension that includes aggressive and religious obsessions, as well. Indeed, the Dimensional Obsessive-Compulsive Scale (DOCS) Unacceptable Thoughts Scale includes obsessional content relating to sexual, violent, and religious themes associated with rituals that are often covert. However, there is reason to suspect that sexual obsessions differ meaningfully from other types of unacceptable thoughts. We conducted two studies to evaluate the factor structure, initial psychometric characteristics, and associated clinical features of a new DOCS scale for sexually intrusive thoughts (SIT). In the first study, nonclinical participants (N=475) completed the standard DOCS with additional SIT questions and we conducted an exploratory factor analysis on all items and examined clinical and cognitive correlates of the different scales, as well as test-retest reliability. The SIT Scale was distinct from the Unacceptable Thoughts Scale and was predicted by different obsessional cognitions. It had good internal consistency and there was evidence for convergent and divergent validity. In the second study, we examined the relationships among the standard DOCS and SIT scales, as well as types of obsessional cognitions and symptom severity, in a clinical sample of individuals with OCD (N=54). There were indications of both convergence and divergence between the Unacceptable Thoughts and SIT scales, which were strongly correlated with each other. Together, the studies demonstrate the potential utility of assessing sexually intrusive thoughts separately from the broader category of unacceptable thoughts.

RESUMEN

Current conceptualizations for anxiety disorders focus heavily on cognitive and behavioral aspects of anxiety and address other emotions to a far lesser extent. Studies have demonstrated that negative appraisals of anxiety and fear (e.g., anxiety sensitivity) are elevated in each of the anxiety disorders and depressive disorders. Much less is known about how the appraisal of other emotions is related to anxiety disorder symptom presentation. The current study examines the appraisal of specific aversive emotions in relation to anxiety symptomatology. Undergraduate university students (N = 530) completed measures of specific anxiety and depressive symptoms, as well as a measure of emotional appraisal. A maximum likelihood estimated multivariate regression model was used to examine the unique relationships between emotional appraisal and anxiety and depressive symptoms. Results indicated that anxiety symptoms varied in their relationships with emotional appraisal. Each symptom group was highly related to fear of appraisals of anxiety; however, some anxiety symptoms were also related to fear of other emotional states, including guilt, sadness, disgust, lust, and embarrassment. Understanding the full range of appraisals of emotional experiences in anxiety conditions may help inform conceptualizations, and potentially treatments, by guiding the focus to the feared emotional states of the individual. The present study helps to clarify some of the relationships between emotion appraisal and anxiety symptoms.

RESUMEN

BACKGROUND: Anterior cruciate ligament reconstruction (ACLR) is standard practice for athletes that wish to return to high-level activities; however functional outcomes after ACLR are poor. Quadriceps strength weakness, abnormal movement patterns and below normal knee function is reported in the months and years after ACLR. Second ACL injuries are common with even worse outcomes than primary ACLR. Modifiable limb-to-limb asymmetries have been identified in individuals who re-injure after primary ACLR, suggesting a neuromuscular training program is needed to improve post-operative outcomes. Pre-operative perturbation training, a neuromuscular training program, has been successful at improving limb symmetry prior to surgery, though benefits are not lasting after surgery. Implementing perturbation training after surgery may be successful in addressing post-operative deficits that contribute to poor functional outcomes and second ACL injury risk. METHODS/DESIGN: 80 athletes that have undergone a unilateral ACLR and wish to return to level 1 or 2 activities will be recruited for this study and randomized to one of two treatment groups. A standard care group will receive prevention exercises, quadriceps strengthening and agility exercises, while the perturbation group will receive the same exercise program with the addition of perturbation training. The primary outcomes measures will include gait biomechanics, clinical and functional measures, and knee joint loading. Return to sport rates, return to pre-injury level of activity rates, and second injury rates will be secondary measures. DISCUSSION: The results of this ACL-Specialized Post-Operative Return To Sports (ACL-SPORTS) Training program will help clinicians to better determine an effective post-operative treatment program that will improve modifiable impairments that influence outcomes after ACLR. TRIAL REGISTRATION: Randomized Control Trial NIH 5R01AR048212-07. ClinicalTrials.gov: NCT01773317.

RESUMEN

OBJECTIVE: The present study examines the effectiveness of a 12-week transdiagnostic cognitive-behavioral group in reducing comorbid diagnoses. METHOD: Data from 79 treatment completers (60.8% women; M age = 32.57 years) during three previous trials of transdiagnostic cognitive behavior therapy (CBT) were examined to compare treatment effects between those with and without comorbid diagnoses. Additionally, rates of remission of comorbid diagnoses were compared to published diagnosis-specific CBT trials. RESULTS: Results indicate that a majority of clients (64.6%) had at least one comorbid disorder and that those with comorbid diagnoses had higher primary diagnosis severity scores than did those without comorbid diagnoses. The presence of a comorbid diagnosis at pretreatment was not associated with differential improvement in primary diagnosis severity following treatment. Two-thirds of completers with comorbid diagnoses at pretreatment (66.7%) no longer met criteria for a clinically severe comorbid diagnosis at posttreatment, a rate higher than that associated with most trials of diagnosis-specific CBT for anxiety disorders used as benchmarks. CONCLUSIONS: These results suggest that transdiagnostic cognitive-behavioral group treatment for anxiety may be associated with greater decreases in comorbidity than traditional diagnosis-specific CBT.

RESUMEN

OBJECTIVE(S): Treatment credibility and client satisfaction have received relatively little research attention, but extant findings indicate that some clients and therapists differ in their perceptions of what is helpful about therapy, with greater divergence related to poorer outcomes. This study examined relationships between treatment credibility, perceptions of therapy helpfulness, and treatment response. METHOD: Participants were 48 individuals (60.4% female; 53.2% Caucasian; mean age 32.79 years) with an anxiety disorder diagnosis. Participants completed a 12-week transdiagnostic treatment protocol; treatment credibility was rated after session 2, and treatment component helpfulness was rated posttreatment. RESULTS: Treatment response was significantly correlated with perceived helpfulness of cognitive restructuring and exposure techniques, but not treatment credibility. Treatment responders recognized the helpfulness of factors considered to be important therapeutic processes. CONCLUSIONS: Findings emphasize the importance of client perceptions of cognitive and behavioral techniques in treatment and suggest the need to monitor client perceptions throughout the treatment process.

RESUMEN

Internet pornography (IP) use has increased over the past 10 years. The effects of IP use are widespread and are both negative (e.g., relationship and interpersonal distress) and positive (e.g., increases in sexual knowledge and attitudes toward sex). Given the possible negative effects of IP use, understanding the definition of IP, the types of IP used, and reasons for IP use is important. The present study reviews the methodology and content of available literature regarding IP use in nondeviant adult populations. The study seeks to determine how the studies defined IP, utilized validated measures of pornography use, examined variables related to IP, and addressed form and function of IP use. Overall, studies were inconsistent in their definitions of IP, measurement, and their assessment of the form and function of IP use. Discussion regarding how methodological differences between studies may impact the results and the ability to generalize findings is provided, and suggestions for future studies are offered.

RESUMEN

Previous research has demonstrated that comorbid obsessive-compulsive personality disorder (OCPD) in patients with obsessive-compulsive disorder (OCD) is associated with greater overall OCD severity, functional impairment, and poorer treatment outcomes (Coles et al., 2008; Lochner et al., 2010; Pinto, 2009). However, research has only examined the effects of OCPD categorically and has yet to thoroughly examine the impact of individual OCPD characteristics dimensionally. Thus, the present study sought to investigate the relationships between various OCPD-related dimensions (e.g., perfectionism, rigidity) and OCD symptomology and severity. The study recruited a sample of OCD patients (n=51) in the OCD units of two residential treatment facilities. Findings yielded significant relationships between OCD severity and the following OCPD dimensions: flexibility, doubts about actions (a dimension of perfectionism), and hoarding. Interpretations of these results and the implications for diagnosis, prognosis, and treatment outcome are discussed. Furthermore, the current study provides insight into a unique perspective which leaves room for more symptom overlap and variability between OCD and OCPD.
