Effective social support: Antecedents and consequences of partner support during pregnancy

This longitudinal study investigated a new conceptualization of the effectiveness of social support attempts called social support effectiveness (SSE) that takes into account the quantity and quality of support attempts and the extent to which they meet the needs of recipients. SSE was assessed in a sample of 176 pregnant women with regard to their partners’ social support behaviors. Potential antecedents of SSE were investigated, including individual and relationship variables. In addition, it was hypothesized that women who appraised their partner’s support as more effective would have lower prenatal anxiety, both concurrently (in mid‐pregnancy) and prospectively (in late pregnancy). Factor analyses confirmed that all hypothesized aspects of SSE contributed to a unitary factor of SSE. Structural equation modeling was used to test the proposed antecedents and consequences of SSE. Results revealed that women’s ratings of the effectiveness of partner support were predicted by their interpersonal orientation (adult attachment, network orientation, kin individualism–collectivism, and social skills) and by characteristics of their relationships with their partners (relationship quality, emotional closeness and intimacy, and equity). Furthermore, women who perceived themselves to have more effective partner support reported less anxiety in mid‐pregnancy and showed a reduction in anxiety from mid‐ to late pregnancy. Findings are discussed with regard to implications for advancing research on social support processes, especially within relationship contexts.     

A COMPARISON OF VALIDATION CRITERIA: OBJECTIVE VERSUS SUBJECTIVE PERFORMANCE MEASURES AND SELF- VERSUS SUPERVISOR RATINGS

This study compared four criteria–two objective (production quantity and production quality) and two subjective (supervisor and self-ratings)–for their predictability in a criterion-related validity study. Results from this sample of 212 maintenance, mechanic, and field service workers replicated previous meta-analytic results with clerical workers (Nathan & Alexander, 1988); supervisor ratings and objective productivity indices provided similar and significant validity coefficients with a unit-weighted composite of five cognitive ability tests. The objective quality index and employee self-ratings resulted in near zero correlations with the same predictor battery. Additional productivity and quality objective criterion data were available for 2 years since the original validation study; no change in validity was found.     

Internal Versus External Control of Reinforcement in Health Risk and HIV and AIDS Prevention

The purpose of the study was to establish the difference in health and HIV and AIDS risk between students with an internal locus of control (LOC; n = 124) and students with an external LOC (n = 133). The study assessed students' LOC and health risks associated with self‐control, fatalism, achievement‐oriented behavior, deferment of gratification, personal values, and alienation. The findings indicate significant differences in health risks between students with an internal LOC and those with an external LOC. Future research should focus on LOC, reinforcement, and HIV and AIDS risk.
