A systematic review evaluating the psychometric properties of measures of social inclusion

Introduction: Improving social inclusion opportunities for population health has been identified as a priority area for international policy. There is a need to comprehensively examine and evaluate the quality of psychometric properties of measures of social inclusion that are used to guide social policy and outcomes. Objective: To conduct a systematic review of the literature on all current measures of social inclusion for any population group, to evaluate the quality of the psychometric properties of identified measures, and to evaluate if they capture the construct of social inclusion. Methods: A systematic search was performed using five electronic databases: CINAHL, PsycINFO, Embase, ERIC and Pubmed and grey literature were sourced to identify measures of social inclusion. The psychometric properties of the social inclusion measures were evaluated against the COSMIN taxonomy of measurement properties using pre-set psychometric criteria. Results: Of the 109 measures identified, twenty-five measures, involving twenty-five studies and one manual met the inclusion criteria. The overall quality of the reviewed measures was variable, with the Social and Community Opportunities Profile-Short, Social Connectedness Scale and the Social Inclusion Scale demonstrating the strongest evidence for sound psychometric quality. The most common domain included in the measures was connectedness (21), followed by participation (19); the domain of citizenship was covered by the least number of measures (10). No single instrument measured all aspects within the three domains of social inclusion. Of the measures with sound psychometric evidence, the Social and Community Opportunities Profile-Short captured the construct of social inclusion best. Conclusions: The overall quality of the psychometric properties demonstrate that the current suite of available instruments for the measurement of social inclusion are promising but need further refinement. There is a need for a universal working definition of social inclusion as an overarching construct for ongoing research in the area of the psychometric properties of social inclusion instruments

The associations between basic psychological need satisfaction at work and the wellbeing of Indigenous and non-Indigenous employees

We investigated how satisfaction of the basic psychological needs at work was associated with the psychological and physical wellbeing of Indigenous and non-Indigenous employees both within and outside of the workplace. Participants included 1,146 Indigenous (n = 559) and non-Indigenous Australians (60.9% female), aged 18 to 81 years (Mage = 43.54) who were recruited through their employer or online advertisements. Structural equation modelling (SEM) was used to analyse the data, and Indigenous status and occupation type were investigated as moderators. Results revealed that independent of income, autonomy satisfaction was related to better physical and psychological health, satisfaction of the need for relatedness was associated with increased family and community thriving, and competence satisfaction was linked to decreased psychological distress. Results also showed that autonomy, competence, and relatedness need satisfaction was lower among Indigenous employees compared to non-Indigenous employees. Moderation analyses suggested that relatedness at work was especially important for non-Indigenous employees’ connection with their community, as were high levels of competence satisfaction for Indigenous employees. These findings are discussed in the context of self-determination theory and the implications for organizations wanting to improve the wellbeing of their Indigenous and non-Indigenous workforce

A cross-cultural investigation of basic psychological need satisfaction at work in an Indigenous and non-Indigenous Australian sample across occupation types

Self-determination theory (SDT) posits universality without cross-cultural uniformity of the three basic psychological needs (autonomy, competence, and relatedness) which have been associated with desirable job outcomes. Yet these promising directions in theory and research have not been extended to Indigenous samples and different occupational types. This is unfortunate as Indigenous peoples globally remain the most disadvantaged on all socio-economic indicators, including employment. This study adopted a strengths-based approach to investigating associations between SDT’s need satisfaction and job outcomes in Australian Indigenous and non-Indigenous professionals and non-professionals. Participants included 1,146 Indigenous (48.8%) and non-Indigenous Australians (39.1% men), aged 18 to 81 years (Mage = 43.54). Structural equation modeling (SEM) revealed that autonomy and competence need satisfaction were associated with multiple positive work outcomes and less job ambiguity, whereas satisfaction of the need for relatedness was associated with increased job satisfaction and greater resilience in the workplace. Moderation by Indigenous status and occupation type revealed few differences in the direction and strength of the associations between need satisfaction and job outcomes. However, non-professionals reported significantly lower satisfaction of all three needs, and Indigenous participants reported significantly lower levels of autonomy need satisfaction. As need satisfaction was shown to be equally beneficial for all workers regardless of culture or occupation type, these findings highlight the need for employers to invest more in cultivating the need satisfaction of their Indigenous and non-professional staff. Overall, the results extend upon previous research by demonstrating that SDT is generalizable to an Australian Indigenous population and that workplace need satisfaction is important for Indigenous and non-professional employee outcomes

Improving sightings-derived residency estimation for whale shark aggregations: A novel metric applied to a global data set

The world’s largest extant fish, the whale shark Rhincodon typus, is one of the most-studied species of sharks globally. The discovery of predictable aggregation sites where these animals gather seasonally or are sighted year-round – most of which are coastal and juvenile-dominated – has allowed for a rapid expansion of research on this species. The most common method for studying whale sharks at these sites is photographic identification (photo-ID). This technique allows for long-term individual-based data to be collected which can, in turn, be used to evaluate population structure, build population models, identify long-distance movements, and assess philopatry and other population dynamics. Lagged identification rate (LIR) models have fewer underlying assumptions than more traditional capture mark recapture approaches, making them more broadly applicable to marine taxa, especially far-ranging megafauna species like whale sharks. However, the increased flexibility comes at a cost. Parameter estimations based on LIR can be difficult to interpret and may not be comparable between areas with different sampling regimes. Using a unique data-set from the Philippines with ~8 years of nearly continuous survey effort, we were able to derive a metric for converting LIR residency estimates into more intuitive days-per-year units. We applied this metric to 25 different sites allowing for the first quantitatively-meaningful comparison of sightings-derived residence among the world’s whale shark aggregations. We validated these results against the only three published acoustic residence metrics (falling within the ranges established by these earlier works in all cases). The results were then used to understand residency behaviours exhibited by the sharks at each site. The adjusted residency metric is an improvement to LIR-based population modelling, already one of the most widely used tools for describing whale shark aggregations. The standardised methods presented here can serve as a valuable tool for assessing residency patterns of whale sharks, which is crucial for tailored conservation action, and can cautiously be tested in other taxa
