Medical outcomes study social support survey (MOS-SSS) in patients with chronic disease: A psychometric assessment

Purpose

Currently, information on the psychometric properties of the Medical outcomes study-social support survey (MOS-SSS) for patients with chronic disease in primary health care, suggests problems in the dimensionality, specifically predominant unidimensionality in a multidimensional measure. The aim of this study was to determine the internal structure (dimensionality, measurement invariance and reliability) and association with other variables.

Methods

A total of 470 patients with chronic disease from a Family Medicine Unit at the Instituto Mexicano del Seguro Social, IMSS, with a mean age of 51.51 years were included. Participants responded to the Questionnaire of Sociodemographic Variables (Q-SV), SF-36 Health-Related Quality of Life Scale-version 1.1, and MOS-SSS.

Results

Non-parametric (Mokken scaling analysis) and parametric (confirmatory factor analysis) analyses indicated unidimensionality, and three-factor model was not representative. A new 8-item version (MOS-S) was developed, where measurement invariance, equivalence with the long version, reliability, and relationship with the SF-36 were satisfactory.

Conclusion

The MOS-SSS scale is unidimensional, and the shortened version yields valid and reliable scores for measuring social support in patients with chronic disease at the primary health care.

Adolescent-Adult Social Networks and Experiences of Violence Among Black Youth in Neighborhoods With High Levels of Community Violence

PURPOSE

Adult support is inversely linked to health-affecting risk behaviors. This study aimed to describe adolescent-adult support network structure and quality, and to analyze associations among network properties, strength of emotional and instrumental support, and violence involvement among predominantly Black youth residing in neighborhoods with high levels of community violence.

METHODS

One hundred six youth from urban neighborhoods with high levels of community violence in Pittsburgh, PA completed egocentric social network surveys describing adult supports, measures of support across contexts, and past 30-day violence perpetration, victimization, and witnessing. Forty youth-identified adults completed complementary social network surveys. Poisson regression examined associations among strength of social support, adults' violence experiences, and youths' violence experiences.

RESULTS

Mean youth participant age was 16.7 years, 56% self-identified as female, and 84% as Black or African-American. Youth and adult participants reported high levels of violence exposure and involvement. Youth identified a mean of 4.8 adult supports. Identifying at least one immediate family member in their network was inversely related to violence perpetration (adjusted incidence rate ratio [aIRR] 0.44, 95% confidence interval [CI] 0.22-0.89), victimization (aIRR 0.42, 95% CI 0.25-0.72), and witnessing (aIRR 0.48, 95% CI 0.35-0.64). The percent of adult supports involved in violence was directly associated with violence perpetration (aIRR 1.81, 95% CI 1.07-3.07), victimization (aIRR 1.95, 95% CI 1.09-3.45), and witnessing (aIRR 1.85, 95% CI 1.25-2.73). Few associations emerged between the structure of youth-reported adolescent-adult social networks and violence.

DISCUSSION

Network-based interventions combined with healing-centered services attuned to violence experiences among Black youth and their adult supports may offer opportunities to leverage youths' existing adult support network and reduce violence.

Development of the quality of teen trauma acute care patient and parent-reported experience measure

Objective

Patient-Reported Experience Measures (PREMs) provide valuable patient feedback on quality of care and have been associated with clinical outcomes. We aimed to test the reliability of a modified adult trauma care PREM instrument delivered to adolescents admitted to hospital for traumatic injuries, and their parents. Modifications included addition of questions reflecting teen-focused constructs on education supports, social network maintenance and family accommodation.

Results

Forty adolescent patients and 40 parents participated. Test-retest reliability was assessed using Cohen’s kappa, weighted kappa, and percent agreement between responses. Directionality of changed responses was noted. Most of the study ran during the COVID-19 pandemic. We established good reliability of questions related to in-hospital and post-discharge communication, clinical and ancillary care and family accommodation. We identified poorer reliability among constructs reflecting experiences that varied from the norm during the pandemic, which included “maintenance of social networks”, “education supports”, “scheduling clinical follow-ups” and “post-discharge supports”. Parents, but not patients, demonstrated more directionality of change of responses by responding with more negative in-hospital and more positive post-discharge experiences over time between the test and retest periods, suggesting risk of recall bias. Situational factors due to the COVID-19 pandemic and potential risks of recall bias may have limited the reliability of some parts of the survey.

Psychometric properties of the Perceived Social Support Questionnaire (PSSQ), a new measure of perceived social support among older adults

OBJECTIVE

Based on literature and available questionnaires, the present study aimed at creating and validating the Perceived Social Support Questionnaire (PSSQ): a 4-item scale assessing the perceived social support in older adults. Normative scores were also computed.

METHODS

Three hundred and two participants (mean age 87.68) selected from ongoing population-based studies completed a phone interview. Among these, 247 completed a second interview 4 months later allowing assessing the questionnaire fidelity over time.

RESULTS

The factor analysis evidenced two dimensions: availability of social support and satisfaction with it. Both dimensions had a satisfactory internal consistency but weak intraclass correlation coefficient. Univariate analyses revealed that age, number of calls per week and living environment marginally associated with the availability score. The satisfaction score was associated with perceived health status, sadness, depressive mood, feeling of loneliness, anxiety, and the perception of social support during the pandemic context. The norms computed were stratified on age.

CONCLUSIONS

The PSSQ is a short and easy-to-administer tool allowing assessing perceived social support in older population. Despite a weak fidelity that could actually be explained by changes in perceived social support over time, the questionnaire revealed good psychometric qualities and validity.

Social support and C-reactive protein in a Québec population cohort of children and adolescents

Objective

Robust evidence exists for the health-enhancing benefits of social support in adults. Inflammatory processes are thought to be an important mechanism linking social support and health risk. Less is known about the relation between social support and chronic inflammation during childhood and adolescence, or when the association emerges during the lifespan.

Method

Data from the population-representative 1999 Quebec Child and Adolescent Health and Social (QCAHS) survey were analyzed. Youth aged 9, 13, and 16 years (N = 3613) and their parents answered questions about social support. A subsample (n = 2186) completed a fasting blood draw that was assayed for C-reactive protein (CRP).

Findings

Higher social support was significantly associated with lower hs-CRP_log, after controlling for age, sex, body mass index (BMI Z-score), medication use, puberty, ethnoracial status (French-Canadian), smoking, household income, and parental education (F = 25.88, p = < .001, Total R²_adj = 10.2%). The association was largely similar for boys and girls, and strengthened with age.

Conclusion

Greater social support was linked to lower chronic low-grade inflammation in a large sample of children and adolescents. Effect sizes were small and consistent with prior findings in the adult literature. Importantly, these findings provide evidence that the relation between social support and inflammation emerges early in the lifespan. Future work should consider broader, more encompassing conceptualizations of social support, the role of social media, and prospective trajectories of social support and inflammatory markers.

Perceived Social Support for a Sustainable Adolescence: A Theoretical Model of Its Sources and Types

Despite the growing interest in perceived social support as a means of achieving sustainable psychological development and well-being in the various contexts of the adolescent, its definition and composition remain unclear. The aim of this study is to test both the hierarchical order and the types and sources of a theoretical model of the social support perceived by adolescents. The model is based on the theories of Tardy and Lin, as well as on the findings of recent studies on the construct. Three theoretical models are compared using the structural equations method. The participants were 1081 randomly selected secondary school students (aged 12–18 years) from the north of Spain, who completed the APIK Perceived Social Support Questionnaire. The model positing that perceived social support comprises a hierarchical first level formed by sources of support (family, friends and teachers) and a lower second level derived from the first one, formed by types of support (emotional, material and informational), proved to be the first-choice solution. The results establish a solid theoretical base for both future studies on perceived social support during adolescence and possible educational interventions designed to improve social support for teenagers.
