Measuring Loneliness Among Middle-Aged and Older Adults: The UCLA and de Jong Gierveld Loneliness Scales

This study examined the measurement and invariance properties of the R-UCLA and de Jong Gierveld loneliness scales for research involving middle-aged and older adults. Confirmatory factor analyses (CFAs) of data from interviews with adults aged 45–84 revealed limited support for the unidimensionality of either scale while subsequent analyses indicated the multidimensionality of both. However, method effects associated with positive and negative item wording were also evident. Multiple group CFAs provided limited support for assumptions of measurement invariance across age groups and from baseline to follow-up with regard to the R-UCLA scale. In contrast, strong measurement invariance across age groups and successive measurements was established for the bi-dimensional dJG scale. Overall, the findings supported the relative utility of the dJG scale for research involving middle-aged and older adults but suggested a need for attention to the implications of method effects associated with item wording and lack of measurement invariance with respect to item residuals.     

Soil Nutrient Depletion and Population Growth in Sub-Saharan Africa: A Malthusian Nexus?

Soil nutrient mining and other forms of soil degradation threaten future soil productivity, especially in sub-Saharan Africa (SSA). Data from 36 countries in SSA show a significant relationship at the supra-national level between soil nutrient depletion (including erosion), reduced fallow periods, and population pressure and thus illustrate the unsustainable population-agriculture-environment nexus on the continent which so far has been described in case studies only. It appears that Malthusian mechanisms are at work, despite encouraging indications of farmers' concerns and adaptation to changing conditions. It is agreed that a re-examination of the common land degradation assessments and farmers' response to changing conditions would be useful, however, this should not delay other recommended interventions.     

Children and the Mental Health of Older Adults in China: What Matters?

China is witnessing several major demographic, socioeconomic, and cultural trends that likely intersect in unique and significant ways to influence the health and well-being of its older adult population. Concerns that such trends may be eroding traditional family structures and values raise questions about the continued importance and impact of children on the lives of their older parents. Do children matter and, if so, what is it about having children that makes a difference to the mental health of their parents? This study addressed these issues using baseline data drawn from the Chinese Longitudinal Aging Social Survey, conducted in 2014. Multivariate OLS regression analyses revealed the importance of having children for parental mental health. This relationship was found to be mediated by economic/utilitarian factors (co-residence, the receipt of financial, and instrumental support) as well as psychological/emotional factors (companionship, emotional support), and social/traditional factors (children’s socioeconomic status achievements). These findings support the view that children continue to be important to the mental health of their older parents in contemporary China. Further, what matters most when it comes to understanding the influence that children have on parents’ mental health are their perceived accomplishments in life and their meaningful presence in the day-to-day lives of their parents.

     

Perpetration,Revictimization, and Self-Injury: Traumatic Reenactments of Child Sexual Abuse in a Nonclinical Sample of South African Adolescents

Risk factors for traumatic reenactments of child sexual abuse experiences (perpetration, revictimization, and self-injury) were examined in a sample of 718 South African secondary school adolescents. Logistic regression analyses indicated that the most consistent predictors of reenactments were a history of child sexual abuse (rape and/or indecent assault) and respondents’ gender, with males being significantly more likely than females to report perpetration (OR = 13.5) and females being more likely to report revictimization (OR = 3.2) and self-injury (OR = 2.5). An analysis restricted to respondents with a history of child sexual abuse indicated that negative abuse-related cognitions were the most consistent predictor of all forms of traumatic reenactment.     

Intermarriage and Social Support Among Canadians in Middle and Later Life

Despite widespread attention to population aging and contemporary increases in racial intermarriage, little is known regarding their joint implications for social support in middle and later life. Drawing on data from the 2007 General Social Survey conducted by Statistics Canada on intermarried and endogamously married adults age 45 and over (N = 13,238), this study examined the effects of intermarriage on instrumental and emotional support. The results revealed that intermarriage was accompanied by a reduced likelihood of instrumental support with transportation from others outside the household but that it had no impact on the receipt of help with household tasks or in caring for family members and a positive impact on emotional support. These findings suggest that intermarriage is not uniformly positive, neutral, or negative in its implications for social support. Future theoretical and empirical work will need to address the complexities of these relationships in order to enhance our understanding of these emergent family structures.
