Background: The Benefit Finding Scale (BFS) is a 17-item measure assessing the perception of positive contributions to one’s life deriving from stressful and life-threatening conditions such as illnesses. We aimed to investigate construct validity (structural validity, measurement invariance between sub-samples, and convergent/divergent validity) and reliability (internal consistency) of the Italian version of the BFS in persons with multiple sclerosis (PwMS) and their caregivers. Methods: We used confirmatory factor analysis (CFA) to assess structural validity in terms of the proposed three-factor structure of the BFS. We performed multi-group CFA to assess measurement invariance between PwMS and their caregivers. To assess convergent/divergent validity, we calculated correlations of the BFS subscales with instruments measuring affect (PANAS), life satisfaction (SWLS), social support (MSPSS), depression (BDI-II), and quality of life (SF-36 and MSQoL-54). To appraise internal consistency, we calculated Cronbach’s alpha. Results: A total of 1359 PwMS and their caregivers completed the study. The three-factor structure of the BFS showed good fit (RMSEA 0.06; CFI 0.92; SRMR 0.05). Configural, metric and scalar invariance were confirmed. Convergent/divergent validity was supported. The BFS showed good internal consistency for ‘Acceptance and adjustment’ (alpha 0.82), ‘Family relations and sense of connectedness’ (alpha 0.84) and ‘Personal growth and authenticity’ (alpha 0.85). Conclusions: Results support the BFS as a valid and invariant three-factor measure of benefit finding among Italian PwMS and their caregivers. This scale use in clinical practice could help health professionals track participants’ experience of positive changes under adverse circumstances, as assets in managing stress and promoting illness adjustment.

Within the framework of the Salutogenic Model of Health, this study aimed to investigate sense of coherence among caregiving partners of persons with multiple sclerosis (PwMS), and its relationship with perceived social support and illness beliefs conceived as generalized resistance resources in tension management. In this cross-sectional study, 398 caregiving partners of PwMS (M_age = 44.62; 34.9% women and 65.1% men) filled in questionnaires measuring sense of coherence (Sense of Coherence Scale-13), perceived social support from family, friends and significant others (Multidimensional Scale of Perceived Social Support), and illness beliefs (Revised Illness Perception Questionnaire). Hierarchical linear regression analysis was performed to assess the contribution of perceived support and illness beliefs to sense of coherence, controlling for sociodemographic and clinical variables. Perceived support from family and beliefs concerning illness-related emotional representations, illness coherence, and treatment control emerged as significant predictors of participants' sense of coherence. Higher perceived support from family and stronger beliefs in illness coherence and treatment control were associated with higher sense of coherence, while more negative emotional representations were related to lower sense of coherence values. Findings lend support to the relevance of a salutogenic approach to caregiving in multiple sclerosis. They further suggest the usefulness of interventions that can promote caregivers' sense of coherence and successful coping in life by benefitting from family support, favoring the construction of a coherent illness view, offering comprehensive information and expert guidance on treatment and rehabilitation opportunities, and promoting adaptive management of negative emotions.

Background: The Multiple Sclerosis Quality of Life-54 (MSQOL-54) is one of the most commonly-used MS-specific health-related quality of life (HRQOL) measures. It is a multidimensional, MS-specific HRQOL inventory, which includes the generic SF-36 core items, supplemented with 18 MS-targeted items. Availability of an adaptive short version providing immediate item scoring may improve instrument usability and validity. However, multidimensional computerized adaptive testing (MCAT) has not been previously applied to MSQOL-54 items. We thus aimed to apply MCAT to the MSQOL-54 and assess its performance.Methods: Responses from a large international sample of 3669 MS patients were assessed. We calibrated 52 (of the 54) items using bifactor graded response model (10 group factors and one general HRQOL factor). Then, eight simulations were run with different termination criteria: standard errors (SE) for the general factor and group factors set to different values, and change in factor estimates from one item to the next set at < 0.01 for both the general and the group factors. Performance of the MCAT was assessed by the number of administered items, root mean square difference (RMSD), and correlation.Results: Eight items were removed due to local dependency. The simulation with SE set to 0.32 (general factor), and no SE thresholds (group factors) provided satisfactory performance: the median number of administered items was 24, RMSD was 0.32, and correlation was 0.94.Conclusions: Compared to the full-length MSQOL-54, the simulated MCAT required fewer items without losing precision for the general HRQOL factor. Further work is needed to add/integrate/revise MSQOL-54 items in order to make the calibration and MCAT performance efficient also on group factors, so that the MCAT version may be used in clinical practice and research.

Research highlighted the negative consequences of the COVID-19 pandemic on adolescents’ emotional well-being worldwide. In the attempt to identify resources which could facilitate adolescents’ adjustment, this study examined the occurrence of flow experience and related activities, and the association between flow and emotional well-being among Italian teenagers. In Spring 2021, 150 students (40.7% girls) aged 15–19 completed instruments assessing flow and related activities before and during the pandemic, and current positive and negative affect. Findings revealed that only 24.7% of the participants currently reported flow; over half of those reporting flow before the pandemic did not experience it subsequently, and only 6.5% of those not reporting flow before the pandemic currently experienced it. Participants with flow both before and during the pandemic reported higher positive affect than teens who never experienced flow (p = .011), or lost it (p = .006). No group differences were detected for negative affect. Learning, structured leisure, and interpersonal relations were the domains most frequently associated with flow before and during the pandemic, but after the pandemic onset a reduction in the variety of flow activities and limited identification of new flow domains were observed. The association of flow with higher emotional well-being even in pandemic times suggests the potential usefulness of interventions promoting flow retrieval under adverse circumstances.
