RESUMEN
OBJECTIVES: This study aimed to investigate the psychometric properties of the Turkish version of the "Caring Ability of Family Caregivers of Patients with Cancer Scale" in parents of children with cancer". METHODS: The current study has a methodological design. The study group consisted of 493 parents of children with oncological problems who were followed in the pediatric hematology-oncology departments of three university hospitals. Data were collected between January and December 2021 through convenience sampling. The face, content construct validity, internal consistency, and scale stability were evaluated. SPSS 26.0 and LISREL 8.80 package programs were used to analyze the data. RESULTS: In the confirmatory factor analysis; root mean- mean square error of approximation, comparative fit index, normed fit index, and non-normed fit index were determined to be 0.08, 0.93, 0.91, and 0.92, respectively. Cronbach's alpha reliability coefficient obtained from the entire scale was calculated to be 0.88, the stability correlation coefficient was 0.84 (p < .005) and the item-total correlation coefficient was calculated between 0.249 and 0.716. CONCLUSIONS: The scale adapted to Turkish culture can be considered a valid and reliable tool for the assessment of the caring ability of family caregivers of patients with cancer. IMPLICATIONS FOR NURSING PRACTICE: The scale can be used to assess parents' caregiving abilities, to determine their strengths and weaknesses. In this respect, it can contribute to the creation of an education plan, the development of parents' caregiving abilities and the increase in the quality of care.
RESUMEN
Background: Research handling structural differences among groups presume that the measurement tool works similarly among the groups and the results of measurements provide similar psychometric properties. Therefore, the aim of the study is to provide evidence for measurement invariance of the construct validity Perceived Health Outcomes of Recreation Scale (PHORS). Methods: The research sample consisted of a total of 1984 adults who exercise, including 864 women and 1120 men during 2021-2022 in Antalya City, Turkey. The MI of the PHORS was tested by multigroup confirmatory factor analyses, which test the invariance of the covariance structures within the scope of structural equation modelling. Invariance tests were gradually conducted for the implicit variables in the model, CFI (comparative fit index criteria) and AIC (Akaike information criterion) were inquired between structural invariance, where no restriction was applied on the analyses and the other invariance tests (metric invariance, scalar invariance and string invariance respectively) where more restraints are applied. Results: The study yielded evidence showing that the measurement model defined for the factor structure of the scale provided measurement invariance by gender. ΔCFI values were ≤0.010 in all subscales for metric and scalar invariance. Conclusion: The items of PHORS represented the same psychological structure, different groups responded to the items in the same way, the constant values in regression equations generated for the items in regression equations were equal/invariable between the groups.
