Pubertal Effects on Adjustment in Girls: Moving from Demonstrating Effects to Identifying Pathways

The present investigation examines mediated pathways from pubertal development to changes in depressive affect and aggression. Participants were 100 white girls who were between the ages of 10 and 14 (M=12.13, SD=.80); girls were from well-educated, middle- to upper-middle class families, and attended private schools in a major northeastern urban area. Three aspects of pubertal development were examined: (a) estradiol categories tapping gonadal maturation; (b) dehydroepiandrosterone sulfate (DHEAS) levels indicating adrenal maturation; and (c) pubertal timing (early vs. other). Three potential mediators were also examined: emotional arousal, attention difficulties, and negative life events. Tests of mediated models indicated that early pubertal timing predicted higher emotional arousal which subsequently predicted increased depressive affect. Negative life events, and possibly attention difficulties, mediated the associations of both estradiol category and DHEAS with aggression. These findings highlight the potential for more intensive investigation of gonadal and adrenal processes in explaining affective changes at puberty.

Effects of girls' hormonal status on depressive and aggressive symptoms over the course of one year

Associations between hormonal and physical status and girls' depressive affect, aggressive affect, and delinquent behavior were studied over the course of one year. Seventy-two White girls, aged 10–14 at initial data collection, were seen twice. Endocrinological status (estradiol, luteinizing hormone [LH], folicle stimulating hormone [FSH], testosterone, and dehydroepiandosterone sulfate [DHEAS] at Time 1, physical development (menarche, secondary sexual characteristics) and maturational timing at Times 1 and 2 were used to predict self- and maternal reports of depressive affect, and self-reports of aggressive affect and delinquent behavior at Time 2. It was posited that initial endocrinological status, as represented by hormonal categories derived by Warren and Brooks-Gunn [(1989) Mood and Behavior at Adolescence: Evidence for Hormonal Factors, Journal of Clinical Endocrinology and Metabolism, Vol. 69, pp. 77–83] and reflecting estradiol, LH, and FSH levels, would be associated with affective expression and delinquent behavior one year later. DHEAS, however, was not expected to be associated with affective expression a year later as it is thought to be more indicative of adrenal changes that are in part environmentally mediated. Initial affective expression was hypothesized to account for more of the variation than prior hormonal status. Hormonal categories predicted depressive and aggressive affect a year later, while DHEAS, physical status, and maturational timing did not. Initial hormonal categories were associated with subsequent reports of delinquent behavior, although not after physical status or prior reports of delinquency were entered into the regression. Initial reports of affective expression accounted for a far greater proportion of the variance in aggressive affect and delinquent behavior than did hormonal or physical status.Received Ph.D. from Institute of Child Development, University of Minnesota.

How Conditioning on Posttreatment Variables Can Ruin Your Experiment and What to Do about It

In principle, experiments offer a straightforward method for social scientists to accurately estimate causal effects. However, scholars often unwittingly distort treatment effect estimates by conditioning on variables that could be affected by their experimental manipulation. Typical examples include controlling for posttreatment variables in statistical models, eliminating observations based on posttreatment criteria, or subsetting the data based on posttreatment variables. Though these modeling choices are intended to address common problems encountered when conducting experiments, they can bias estimates of causal effects. Moreover, problems associated with conditioning on posttreatment variables remain largely unrecognized in the field, which we show frequently publishes experimental studies using these practices in our discipline's most prestigious journals. We demonstrate the severity of experimental posttreatment bias analytically and document the magnitude of the potential distortions it induces using visualizations and reanalyses of real‐world data. We conclude by providing applied researchers with recommendations for best practice.     

What Interventions Work Best for Families Who Experience Homelessness? Impact Estimates from the Family Options Study

What housing and service interventions work best to reduce homelessness for families in the United States? The Family Options Study randomly assigned 2,282 families recruited in homeless shelters across 12 sites to priority access to one of three active interventions or to usual care in their communities. The interventions were long‐term rent subsidies, short‐term rent subsidies, and transitional housing in supervised programs with intensive psychosocial services. In two waves of follow‐up data collected 20 and 37 months later, priority access to long‐term rent subsidies reduced homelessness and food insecurity and improved other aspects of adult and child well‐being relative to usual care, at a cost 9 percent higher. The other interventions had little effect. The study provides support for the view that homelessness for most families is an economic problem that long‐term rent subsidies resolve and does not support the view that families must address psychosocial problems to succeed in housing. It has implications for focusing government resources on this important social problem.     

Adolescent suicide myths in the United States

In the United States, teen suicide rates tripled over several decades, but have declined slightly since the mid-1990s. Suicide, by its nature, is a complex problem. Many myths have developed about individuals who complete suicide, suicide risk factors, current prevention programs, and the treatment of at-risk youth. The purpose of this article is to address these myths, to separate fact from fiction, and offer recommendations for future suicide prevention programs. Myth #1: Suicide attempters and completers are similar Myth #2: Current prevention programs work. Myth #3: Teenagers have the highest suicide rate. Myth #4: Suicide is caused by family and social stress. Myth #5: Suicide is not inherited genetically. Myth #6: Teen suicide represents treatment failure. Psychiatric illnesses are often viewed differently from other medical problems. Research should precede any public health effort, so that suicide prevention programs can be designed, implemented, and evaluated appropriately. Too often suicide prevention programs do not use evidence-based research or practice methodologies. More funding is warranted to continue evidence-based studies. We propose that suicide be studied like any medical illness, and that future prevention efforts are evidence-based, with appropriate outcome measures.

Neighborhood climates of legal cynicism and complaints about abuse of police power†

Research findings show that legal cynicism—a cultural frame in which skepticism about laws, the legal system, and police is expressed—is important in understanding neighborhood variation in engagement with the police, particularly in racially isolated African American communities. We argue that legal cynicism is also useful for understanding neighborhood variation in complaints about police misconduct. Using data on complaints filed in Chicago between 2012 and 2014, we show that grievances disproportionately came from racially segregated neighborhoods and that a measure of legal cynicism from the mid-1990s predicts complaints about abuse of police power two decades later. The association between legal cynicism and complaints is net of prior complaints, reported crime, imprisonment, and other structural factors that contribute to the frequency and nature of interactions involving police and residents. Legal cynicism also mediates the influence of racially isolated neighborhoods on complaints. The mid-1990s is the approximate midpoint of a half-century of police scandals in Chicago. Our research findings suggest that contemporary complaints about police misconduct in highly segregated Chicago neighborhoods are grounded in collectively shared historical memories of police malfeasance. They also suggest that persistent complaints about police misconduct may represent officially memorialized expressions of enduring racial protest against police abuse of power.
