Maternal work early in the lives of children and its distal associations with achievement and behavior problems: a meta-analysis.

This meta-analysis of 69 studies (1,483 effect sizes) used random effects models to examine maternal employment during infancy/early childhood in relation to 2 major domains of child functioning: achievement and behavior problems. Analyses of studies that spanned 5 decades indicated that, with a few exceptions, early employment was not significantly associated with later achievement or internalizing/externalizing behaviors. The exceptions were for teacher ratings of achievement and internalizing behaviors: Employment was associated with higher achievement and fewer internalizing behaviors. Substantial heterogeneity among the effect sizes prompted examination of moderators. Sample-level moderator analyses pointed to the importance of socioeconomic and contextual variables, with early employment most beneficial when families were challenged by single parenthood or welfare status. Maternal employment during Years 2 and 3 was associated with higher achievement. Some moderator analyses indicated negative effects of employment for middle-class and 2-parent families and for very early employment (child's first year). Associations also differed depending on whether effect sizes were adjusted for contextual variables. Only 1 study-level moderator (sex of first author) was significant after adjusting for other moderators. The small effect size and primarily nonsignificant results for main effects of early maternal employment should allay concerns about mothers working when children are young. However, negative findings associated with employment during the child's first year are compatible with calls for more generous maternal leave policies. Results highlight the importance of social context for identifying under which conditions and for which subgroups early maternal employment is associated with positive or negative child outcomes.

Substance use after residential treatment among individuals with co-occurring disorders: the role of anxiety/depressive symptoms and trauma exposure.

This longitudinal study examined the contribution of anxiety/depressive symptoms and lifetime and recent trauma exposure to substance use after residential substance abuse treatment among individuals with co-occurring disorders. Data were collected from adults at treatment entry and 6 and 12 months later. At treatment entry, nearly all participants reported lifetime trauma exposure, and over one third met criteria for posttraumatic stress disorder (PTSD). Over the follow-up, nearly one third of the participants were exposed to trauma. Lifetime trauma exposure and a diagnosis of PTSD at treatment entry were not associated with substance use over the follow-up. Trauma exposure and anxiety/depressive symptoms over the follow-up were associated with an increased likelihood of substance use. Gender did not moderate the association between trauma exposure and anxiety/depressive symptoms and substance use. These findings highlight the importance of monitoring for trauma exposure and symptoms of anxiety/depression to better target interventions and continuing care approaches to reduce the likelihood of posttreatment substance use in this population.

Income volatility and psychological depression.

Income volatility appears to be increasing especially among lower income workers. Such volatility may reflect the ongoing shift of economic risk from employers to employees as marked by decreasing job security and employer-provided benefits. This study tests whether absolute volatility or downward volatility in income predict depression controlling for prior depression. A sample (n = 4,493) from the National Longitudinal Survey of Youth (NLSY79) with depression (CESD) measured at age 40 and prior depression measured eight to 10 years earlier was utilized. Downward volatility (frequency of income loss) was positively associated with depression; adjusting for downward volatility and other covariates, absolute volatility was negatively associated with depression. An interaction indicated a positive association between downward volatility and depression only when absolute volatility was high. These findings apply to respondents in a narrow age range (30 s) and the results warrant replication to identify the mediators linking absolute volatility and income loss to depression.

Maternal employment and children's achievement in context: a meta-analysis of four decades of research.

This meta-analysis of 68 studies (770 effect sizes) used random effects models to examine whether children's achievement differed depending on whether their mothers were employed. Four achievement outcomes were emphasized: formal tests of achievement and intellectual functioning, grades, and teacher ratings of cognitive competence. When all employment was compared with nonemployment for combined and separate achievement outcomes without moderators, effects were nonsignificant. Small beneficial effects of part-time compared with full-time employment were apparent for all achievement outcomes combined and for each individual achievement outcome. Significant sample-level moderators of the associations between maternal employment and achievement for all outcomes combined included family structure, race/ethnicity, and socioeconomic status; associations were positive when samples were majority 1-parent families and mixed 1- and 2-parent families, racially/ethnically diverse or international in composition, and not middle-upper class. Analyses of child gender indicated more positive effects for girls. Children's age was a significant moderator for the outcome of intellectual functioning. The identification of sample-level moderators of the relationship between maternal employment and children's achievement highlights the importance of social context in understanding work-family linkages.

Physical and mental health costs of traumatic war experiences among Civil War veterans.

BACKGROUND: Hundreds of thousands of soldiers face exposure to combat during wars across the globe. The health effects of traumatic war experiences have not been adequately assessed across the lifetime of these veterans. OBJECTIVE: To identify the role of traumatic war experiences in predicting postwar nervous and physical disease and mortality using archival data from military and medical records of veterans from the Civil War. DESIGN: An archival examination of military and medical records of Civil War veterans was conducted. Degree of trauma experienced (prisoner-of-war experience, percentage of company killed, being wounded, and early age at enlistment), signs of lifetime physician-diagnosed disease, and age at death were recorded. SETTING AND PARTICIPANTS: The US Pension Board surgeons conducted standardized medical examinations of Civil War veterans over their postwar lifetimes. Military records of 17,700 Civil War veterans were matched to postwar medical records. MAIN OUTCOME MEASURES: Signs of physician-diagnosed disease, including cardiac, gastrointestinal, and nervous disease; number of unique ailments within each disease; and mortality. RESULTS: Military trauma was related to signs of disease and mortality. A greater percentage of company killed was associated with signs of postwar cardiac and gastrointestinal disease (incidence risk ratio [IRR], 1.34; P < .02), comorbid nervous and physical disease (IRR, 1.51; P < .005), and more unique ailments within each disease (IRR, 1.14; P < .005). Younger soldiers (<18 years), compared with older enlistees (>30 years), showed a higher mortality risk (hazard ratio, 1.52), signs of comorbid nervous and physical disease (IRR, 1.93), and more unique ailments within each disease (IRR, 1.32) (P < .005 for all), controlling for time lived and other covariates. CONCLUSIONS: Greater exposure to death of military comrades and younger exposure to war trauma were associated with increased signs of physician-diagnosed cardiac, gastrointestinal, and nervous disease and more unique disease ailments across the life of Civil War veterans. Physiological mechanisms by which trauma might result in disease are discussed.

Birth weight and mothers' adverse employment change.

Low birth weight has been linked at the aggregate level to unemployment rates and at the individual level to subjective distress. We hypothesize that maternal underemployment, including unemployment, involuntary part-time work, and low wage work predicts decreased birth weight. The relationship of birth weight to maternal employment changes during pregnancy was studied prospectively in 1,165 singleton first births in the National Longitudinal Survey of Youth data set. Controlling for other significant risk factors, women who shifted from adequate employment to underemployment had significantly lighter babies. Plausible mediators of this relationship were explored, including prenatal health care, gestational age, and mother's weight gain, with results varying by type of underemployment. Two interactions also suggested that underemployment reduced the beneficial effect of mother's weight gain on birth weight. These findings were partially replicated for low birth weight (< 2,500 grams), indicating the medical significance of the effect.

Mental health and welfare transitions: depression and alcohol abuse in AFDC women.

From a selection perspective, does prior dysfunction select women into welfare or serve as a barrier to leaving welfare? From a social causation perspective, does entering or exiting welfare lead to changes in well being? These questions were analyzed in panel data for over 3,600 women drawn from the National Longitudinal Survey of Youth for the period 1992-94. Welfare is associated with both depression and alcohol consumption cross-sectionally. This link appears to derive in small part from selection into welfare by depression (in interaction with marital status), butdepression and alcohol abuse did not operate as barriers to leaving welfare. Entering welfare was clearly associated with increased depression and alcohol consumption, but confidence in an apparent beneficial effect on alcohol symptoms of leaving welfare for employment was limited by small sample sizes. These findings are located in the context of the 1996-welfare reform and the recent economic expansion. One implication is that community psychology should consider welfare entry as a risk factor similar to adverse employment changes such as job loss.
