RESUMO
Women have smaller cortisol responses to psychological stress than men do, and women taking hormonal contraceptives (HC+) have smaller responses than HC- women. Cortisol secretion undergoes substantial diurnal variation, with elevated levels in the morning and lower levels in the afternoon, and these variations are accompanied by differences in response to acute stress. However, the impact of HC use on these diurnal relationships has not been examined. We tested saliva cortisol values in 744 healthy young adults, 351 men and 393 women, 254 HC- and 139 HC+, who were assigned to morning (9:00 am) or afternoon (1:00 pm) test sessions that were held both on a rest day and on a stress day that included public speaking and mental arithmetic challenges. Saliva cortisol responses to stress were largest in men and progressively smaller in HC- and in HC+ women (F = 23.26, p < .0001). In the morning test sessions, HC+ women had significantly elevated rest day cortisol levels (t = 5.99, p ⪠.0001, Cohen's d = 0.95) along with a complete absence of response on the stress day. In the afternoon sessions, both HC+ and HC- women had normal rest-day cortisol levels and normal responses to the stressors. Heart rates at rest and during stress did not vary by time of day or HC status. Cortisol stress responses in HC+ women are absent in the morning and normal in size by early afternoon. Studies of stress reactivity should account for time of day in evaluating cortisol responses in women using hormonal contraceptives.

BACKGROUND: Risk for alcoholism may be enhanced by exposure to early-life adversity (ELA) in persons with genetic vulnerabilities. We examined ELA in the presence of a common variant of the gene for the enzyme catechol-O-methyltransferase (COMT, Val158Met, rs4680) in relation to cortisol reactivity, the onset of early drinking, and experimentation with drugs. METHODS: Saliva cortisol reactivity to speech and mental arithmetic stress was measured in 480 healthy young adults (23.5 years of age, 50% females) who experienced either 0, 1, or ≥ 2 forms of ELA during childhood and adolescence, provided information on use of alcohol and recreational drugs, and were genotyped for the Val158Met polymorphism. RESULTS: ELA led to progressively smaller cortisol responses in the Met/Met and Val/Met allele groups but to progressively larger responses in Val homozygotes, F = 3.29, p = 0.011. ELA independently predicted earlier age at first drink, F = 14.2, p < 0.0001, with a larger effect in Met-allele carriers, F = 13.95, p < 0.00001, and a smaller effect in Val homozygotes, F = 4.14, p = 0.02. Similar effects were seen in recreational drug use. Cortisol reactivity was unrelated to drinking behavior or drug experimentation. CONCLUSIONS: ELA leads to blunted stress reactivity and, independently, contributes to potentially risky drinking and drug-use behaviors in persons carrying 1 or 2 copies of the COMT 158Met allele. The results reinforce the impact of early experience on the stress axis and on risky behaviors, and they point to the 158Met allele as conveying a vulnerability to the early environment.

OBJECTIVE: Exposure to stress during critical periods of development can diminish stress reactivity by the hypothalamic-pituitary-adrenocortical axis. Genetic characteristics may further modify this effect of early adversity, leading to a gene by environment (G × E) interaction on stress reactivity in adulthood. Val-allele carriers of a common polymorphism of the COMT gene (Val158Met, rs4680) have rapid removal of catecholamines in the prefrontal cortex, limbic system, and reward centers. Carriers of the Val and Met alleles may therefore respond differently to the environment and differ in the long-term impact of exposure to early life adversity (ELA). METHODS: We measured saliva cortisol reactivity to public speaking and mental arithmetic stress in 252 healthy young adults exposed to low, medium, and high levels of ELA and who were genotyped for the Val158Met polymorphism. RESULTS: Cortisol responses showed a G × E interaction (F(4,243) = 2.78, p = .028); simple effects tests showed that Met/Met carriers had progressively smaller cortisol responses with greater levels of ELA. In comparison, Val/Val homozygotes had blunted responses that did not vary with ELA exposure. CONCLUSIONS: Met/Met homozygotes seem sensitive to stressful events in childhood and adolescence, leading to environmental programming of the stress axis. Glucocorticoid responsivity may represent a common pathway revealing targeted genetic vulnerabilities to the long-term effects of early life stress. The results suggest that further G × E studies of ELA are warranted in relation to health behaviors and health outcomes in adulthood.

BACKGROUND: Central serotonergic (5-HT) function is implicated in pathways to alcohol dependence, including dysphoria manifested by symptoms of anxiety and depression. However, little is known about genetic variation in central 5-HT function and its potential impact on temperament and behavior in persons with a family history of alcoholism (FH+). METHODS: We tested 314 healthy young adults (23.5 years of age, 57% female; 193 FH- and 121 FH+) enrolled in the Oklahoma Family Health Patterns project, a study of alcoholism risk in relation to temperament and behavioral dyscontrol. Dysphoria was assessed using the Eysenck neuroticism and Beck depression scales, and Cloninger's Tridimensional Personality Questionnaire. Risk taking was assessed with the Iowa Gambling Task (IGT) and Balloon Analogue Response Task (BART). All subjects were genotyped for a functional polymorphism (5-HTTLPR) in the promoter region of the serotonin transporter gene (SLC6A4). RESULTS: FH+ subjects with the gain-of-function 5-HTTLPR genotype scored higher in neuroticism, harm avoidance, and symptoms of depression (p-values ≤ 0.03). No effect of 5-HTTLPR genotype was seen in FH-. FH+ carriers of the gain-of-function 5-HTTLPR genotype played to minimize their frequency of losses in the IGT, whereas FH- carriers played a balanced strategy (p < 0.003). No 5-HTTLPR effects were seen in the BART. Results were unaffected by sex, education, drug use, and antisocial characteristics. CONCLUSIONS: The functional 5-HTTLPR polymorphism predicted significant variation in negative moods and poorer affect regulation in FH+ persons, with possible consequences for behavior, as seen in a simulated gambling task. This pattern may contribute to a drinking pattern that is compensatory for such affective tendencies.

OBJECTIVES: Feldman (2011) has proposed a new approach to the treatment of posttraumatic stress disorder (PTSD) in individuals at the end-of-life known as Stepwise Psychosocial Palliative Care (SPPC). This approach helps to compensate for the disadvantages of existing PTSD interventions with regard to treating patients with life-limiting and terminal illnesses by employing a palliative care philosophy. The model relies on cognitive and behavioral techniques drawn from evidence-based approaches to PTSD, deploying them in a stage-wise manner designed to allow for interventions to track with patents' needs and prognoses. Because this model is relatively new, we seek to explore issues related to its implementation in the complex settings in which providers encounter patients at the end-of-life. We also seek to provide concrete guidance to providers regarding the management of PTSD at the end-of-life in diverse palliative care settings. METHODS: We examine three specific cases in which the SPPC model was utilized, highlighting particular treatment challenges and strategies. These case studies provide information regarding the SPPC model's application to patients in two distinct palliative care settings-a palliative care consult team and an inpatient palliative care unit. RESULTS: The SPPC model's stage-wise approach allows for its flexible use given a variety of constraints related to setting and patient issues. SIGNIFICANCE OF RESULTS: The SPPC model provides an alternative to existing psychosocial treatments for PTSD that may be more appropriate for patients at the end of life.

BACKGROUND: Stressful early life experience may have adverse consequences in adulthood and may contribute to behavioral characteristics that increase vulnerability to alcoholism. We examined early life adverse experience in relation to cognitive deficits and impulsive behaviors with a reference to risk factors for alcoholism. METHODS: We tested 386 healthy young adults (18 to 30 years of age; 224 women; 171 family history positive for alcoholism) using a composite measure of adverse life experience (low socioeconomic status plus personally experienced adverse events including physical and sexual abuse and separation from parents) as a predictor of performance on the Shipley Institute of Living scale, the Stroop color-word task, and a delay discounting task assessing preference for smaller immediate rewards in favor of larger delayed rewards. Body mass index (BMI) was examined as an early indicator of altered health behavior. RESULTS: Greater levels of adversity predicted higher Stroop interference scores (F = 3.07, p = 0.048), faster discounting of delayed rewards (F = 3.79, p = 0.024), lower Shipley mental age scores (F = 4.01, p = 0.019), and higher BMIs in those with a family history of alcoholism (F = 3.40, p = 0.035). These effects were not explained by age, sex, race, education, or depression. CONCLUSIONS: The results indicate a long-term impact of stressful life experience on cognitive function, impulsive behaviors, and early health indicators that may contribute to risk in persons with a family history of alcoholism.

BACKGROUND: Increased discounting of delayed rewards may be a premorbid characteristic and possible risk factor for alcohol and other drug use disorders; however, previous studies have found no or minimal differences in delay discounting in individuals at risk for substance use disorders based on family history. It is possible that increased delay discounting may be more closely associated with antisocial traits, evident in a subset of individuals with positive family histories of alcohol and drug use disorders, and that previous studies were underpowered for detecting subtle to modest overall group differences. METHODS: In this study, we compared 143 young adults with family histories of alcohol and other drug use disorders (FH+) and 155 young adults with no such histories (FH-) on delay discounting and subsequently examined how delay discounting was related to antisocial traits and other selected psychological and demographic variables. RESULTS: The FH+ group discounted delayed rewards more than the FH- group. Subsequent analyses revealed that increased delay discounting was correlated with having more parents and grandparents with alcohol and drug use disorders, more antisocial traits, more depressive tendencies and lower IQs, and lower income. After controlling for all these relationships, more antisocial traits and lower IQ still predicted greater delay discounting, and subsequent analysis revealed that the greater delay discounting in the FH+ group was mediated by this group's greater number of individuals with antisocial traits. CONCLUSION: FH+ individuals who discount delayed rewards more may be at increased risk for developing alcohol and other drug use disorders; however, additional descriptive studies and longitudinal studies are needed.

BACKGROUND: Abstinent alcoholics have deficits in comprehending the affective intonation in speech. Prior work suggests that these deficits are due to alcohol exposure rather than preexisting risk factors for alcoholism. The present paper examines whether family history of alcoholism is a contributor to affective prosody deficits in alcoholics. METHODS: Fifty-eight healthy, nonabusing young adults with and without a family history of alcoholism or other substance abuse (29 FH+ and 29 FH-) were compared on affective prosody comprehension using the Aprosodia Battery. A secondary analysis was done comparing affective prosody comprehension in FH+ and FH- detoxified alcoholics from an earlier study (17 FH+ and 14 FH-). RESULTS: Performance on the Aprosodia Battery was not related to FH status in either the healthy, nonabusing sample or in the detoxified alcoholic group. CONCLUSIONS: The present study lends support to previous research suggesting that deficits in affective prosody comprehension observed in detoxified alcoholics are associated with a history of heavy drinking rather than with a family history of alcoholism.

BACKGROUND AND AIMS: People with blunted stress reactivity have poor impulse control and also show increased risk for alcoholism. Exposure to early life adversity (ELA) contributes to blunted reactivity, but individual differences in susceptibility to ELA are not well understood. This study aimed to determine whether exposure to ELA has a greater impact on stress reactivity in young adults with a family history of alcoholism (FH+) compared with young adults with no family history of alcoholism (FH-). DESIGN: Observational study using linear modeling. SETTING: Oklahoma, USA. PARTICIPANTS: Seven hundred and nine young adults (398 females) recruited through community advertisement. MEASUREMENTS: We obtained heart rates and cortisol levels in subjects while undergoing public speaking and mental arithmetic stress compared with a resting control day (1418 test sessions). ELA was quantified as 0, 1 or > 1 adverse events experienced by age 15 years. FH+ people had one or two parents with an alcohol use disorder, and FH- controls had no such history for two generations. FINDINGS: Increasing levels of ELA predicted progressive blunting of cortisol and heart rate reactivity for the whole sample (Fs = 4.57 and 4.70, Ps ≤ 0.011), but examination by FH status showed that the effect of ELA was significant only among FH+ (Fs ≥ 3.5, Ps < 0.05) and absent in FH- (Ps > 0.40). This difference in ELA impact was not explained by the cortisol diurnal cycle or subjective evaluation of the stressors. CONCLUSIONS: People with a family history of alcoholism appear to be vulnerable, in terms of changes to physiological stress response, to the impact of exposure to early life adversity while people with no family history of alcoholism appear to be resilient. Blunted stress reactivity may reflect differential vulnerability to early life adversity in young adults with a family history of alcoholism.

BACKGROUND: Some individuals are resistant to alcohol use disorders despite high levels of intake. Addiction Resistance (AR) measures the disparity between alcohol consumption and alcohol use disorder (AUD) symptoms, such that some persons exhibit few (AUD) symptoms despite higher intake. The validity of the concept and the factors contributing to AR are not well understood. The aim of this study was to predict AR based on variables related to risk for addiction that are measured in the Family Health Patterns Project. METHOD: Participants were healthy young adults (nâ¯=â¯1122) with and without a family history of alcohol and other substance use disorders who were given measures of mood stability and risk-taking tendencies, and were interviewed to determine alcohol intake, AUD symptoms, and other substance use disorders (SUD). AR was calculated using maximal lifetime alcohol intake and number of AUD symptoms. RESULTS: A principal components analysis was run with varimax rotation, which yielded three components: Component 1 indexed behavioral and mood regulation, Component 2 encompassed family and environmental factors, and Component 3 included cognitive factors. A multiple regression analysis revealed that Component 1 and Component 2 were predictive of AR whereas Component 3 was not. DISCUSSION: Individuals who reported greater emotional stability, norm adherence, risk avoidance, and fewer family members with substance use disorders were more resistant to AUD despite higher alcohol intake. These findings suggest that AUD risk and resistance may represent different points of the same continuum.

Early life adversity (ELA) negatively affects health behaviors in adulthood, but pathways from ELA exposure to behavioral outcomes are poorly understood. ELA in childhood and adolescence may translate into adult outcomes by way of modified glucocorticoid signaling. The cortisol cotransporter, FKBP5 has a G-to-A substitution (rs9296158) that hinders cortisol trafficking within target cells, and this impaired glucocorticoid signaling may shape the long-term response to ELA. We used performance on the Stroop test to assess working memory in 546 healthy young adults who had experienced 0, 1, or > 1 forms of ELA in childhood and adolescence and were genotyped for the FKBP5 rs9296158 G-to-A polymorphism. We observed a robust Gene x Environment interaction (F = 9.49, p < .0001) in which increased ELA exposure led to progressively greater Stroop interference in persons carrying AG and AA genotypes of FKBP5 with no such effect in GG carriers. Further work is needed to explore the modification of cognitive function resulting from ELA. Impairments in working memory illustrate how ELA may use glucocorticoid pathways to influence working memory with potential implications for decision-making and risky behavior including substance use disorders.

BACKGROUND: Behavioral undercontrol may contribute to risk for alcoholism in vulnerable persons. We predicted that healthy young adults with a family history of alcoholism (FH+) who also displayed externalizing behavior characteristics (low scores on the California Psychological Inventory Sociability Scale; CPI-So) would exhibit more impulsive responding (false alarms) on a Go-NoGo reaction time task. METHODS: Subjects were 230 healthy volunteers, 18 to 30 years of age with no history of alcohol or drug dependence. The task included 100 trials: 60 of "Go," calling for a button press, and 40 of "NoGo," or "XX," calling for inhibiting a response. Data analysis involved a signal detection analysis of performance with subsequent group comparisons for rates of impulsive responding indicated by False Alarms (responses to NoGo signals). RESULTS: CPI-So scores were lower in FH+ than in FH- (p < .000001) indicating a greater clustering of disinhibitory tendencies in these persons. FH, CPI-So scores, and Gender together predicted false alarm rates, accounting for 4.9% of the variance, F = 3.89, p = 0.009. False alarms were associated with low CPI-So scores, F = 5.15, p = 0.024, and being male, F = 6.27, p = 0.013, but not with FH once these variables were accounted for. CONCLUSIONS: A disinhibited temperament may underlie a behavioral impulsivity that contributes to elevated risk for future alcoholism, especially among FH+ males.

Early life adversity (ELA) contributes to behavioral impulsivity along with risk for substance use disorders, both accompanied by blunted stress-axis reactivity. However, the biological contributors to blunted stress reactivity are not known. We took advantage of the fact that women have significant opioid inhibition of cortisol output by using the opioid antagonist, naltrexone, to unmask opioid interactions due to ELA. We administered 50 mg of naltrexone or placebo to 72 healthy women (23 years of age) in a double-blind crossover study and observed deviations in cortisol secretion from placebo over the next 180 minutes. ELA was assessed by reported exposure to physical and sexual abuse or neglect and low socioeconomic status and scored as Low, Medium, or High (0, 1-2, and 3+). The ELA groups all had identical placebo-day cortisol secretion, indicating normal basal regulation of the hypothalamic-pituitary-adrenocortical axis. Cortisol rises to naltrexone were largest in the Low-ELA group and strongly blunted in the High-ELA group (F = 3.51, p = 0.035), indicating a lack of opioid function in women with high degrees of ELA. The Low-ELA women reported dysphoric responses to naltrexone (F = 4.05, p = .022) indicating a mild opioid withdrawal, an effect that was absent in the High-ELA group. Women exposed to ELA have blunted cortisol responses to naltrexone, indicating reduced opioid regulation of the stress axis. Central opioid changes may be one pathway linking ELA to blunted stress reactivity in adulthood.

Abstinent alcoholics show a blunted stress cortisol response that may be a consequence of drinking or a preexisting risk marker. We tested cortisol responses to psychological stress in 186 18-30 year-old, healthy social drinkers having no personal history of alcohol or drug dependence, 91 of whom had one or two alcoholic parents (FH+) and 95 having no family alcoholism for two generations (FH-). We predicted that, similar to alcoholic patients, the FH+ would have reduced stress cortisol responses that would be partially determined by their temperament characteristics, specifically antisocial tendencies as measured by the California Psychological Inventory. On a stress day, subjects performed continuous simulated public speaking and mental arithmetic tasks for 45 min, and on a control day they sat and rested for the same time period. The FH+ who were low in sociability had smaller cortisol responses than FH-, high-sociability persons (t=2.27, p=.02). These two groups were not different in diurnal cortisol secretion patterns or affective responses to the stressors. Persons with a familial risk for alcoholism who have more antisocial tendencies may have altered central nervous system responses to emotionally relevant social challenges. Disrupted cortisol stress responses may serve as a risk marker for the development of substance use disorders.

Alcohol use problems among older adults have been called the "invisible epidemic." As the population of older adults continues to grow, there is an increased need to reexamine alcohol use in this population. The authors provide an overview on alcohol use in the over-60 age group. The main areas of focus included research on the prevalence of drinking in that population, as well as comments on the best practices in assessment and psychological treatment. Several screening assessments have been recommended for use with older adults, such as the CAGE questionnaire, Michigan Alcohol Screening Test-Geriatric version, Alcohol-Related Problems Survey, and the Alcohol Use Disorders Identification Test. The authors note age-appropriate psychological treatment interventions that include brief interventions, family interventions, motivational counseling, and cognitive behavioral therapies. Barriers to assessment and treatment are also discussed.

Exposure to stress during critical periods of development can have adverse effects on adult health behaviors, and genetic vulnerabilities may enhance these stress effects. We carried out an exploratory examination of psychological, physiological, and behavioral characteristics of 252 healthy young adults for the impact of early-life adversity (ELA) in relation to the G-to-A single nucleotide polymorphism (SNP), rs9296158, of the FKBP5 gene. FKBP5 is a molecular cochaperone that contributes to the functional status of the glucocorticoid receptor (GR) and to the quality of corticosteroid signaling. FKBP5 expression is upregulated by cortisol exposure during stressful episodes, with greater upregulation seen in A-allele carriers. As such, FKBP5 expression and GR function may be environmentally sensitive in A-allele carriers and therefore suitable for the study of gene-by-environment (G × E) interactions. Compared with FKBP5, GG homozygotes (N=118), A-allele carriers (N = 132) without psychiatric morbidity had progressively worse performance on the Stroop color-word task with increasing levels of ELA exposure (Genotype × ELA, F=5.14, P=0.007), indicating a G × E interaction on working memory in early adulthood. In addition, heart rate response to mental stress was diminished overall in AA/AG-allele carriers (F=5.15, P=0.024). Diminished working memory and attenuated autonomic responses to stress are both associated with risk for alcoholism and other substance use disorders. The present data suggest that FKBP5 in the GR pathway may be a point of vulnerability to ELA, as seen in this group of non-traumatized young adults. FKBP5 is accordingly a potential target for more extensive studies of the impact of ELA on health and health behaviors in adulthood.

As the population of older adults continues to grow, there will be a simultaneous increase in the number of informal spousal and family caregivers. Given the demands of caregiving, informal caregivers are at risk for significant mental and physical health problems. Since many patients are dependent upon the caregiver to assist them with health-care needs, identifying caregiver needs and making appropriate referrals during patient visits is vital to ensuring quality care for your primary patient. The three main objectives for this review article are to 1) Provide an overview of negative mental and physical health consequences of caregiver stress, 2) Discuss the benefits to both patient and caregiver of addressing caregiver stress, and 3) Suggest ways in which caregiver stress can be identified and resources provided in health clinics with minimal staff time. A bibliography of resources for health care staff, patients, and families is included at the conclusion of the article.

AIM: This study examined the impact of early lifetime adversity (ELA) on affect regulation and personality in persons with family history (FH+) and without (FH-) a family history of alcoholism. We examined the impact of early life adversity in healthy young adults, 18-30 years of age enrolled in a long-term study on risk for alcohol and other substance abuse. METHODS: ELA was assessed by a composite score of low socioeconomic status and personal experience of physical or sexual abuse and/or separation from parents before age 16, resulting in a score of 0, 1-2, or >3 adverse events. Unstable affect regulation and personality variables were obtained via self-report measures. RESULTS: Higher ELA scores were seen in FH+ (χ(2)=109.2, p<0.0001) and in women (χ(2)=17.82, p=0.0019). Although higher ELA predicted less emotional stability and more behavioral undercontrol, further analysis including both FH and ELA showed that FH+ persons are prone to poor affect regulation, negative moods, and have risky drinking and drug abuse tendencies independent of ELA level. ELA predicts reduced stress reactivity and poorer cognitive control over impulsive behaviors as shown elsewhere. CONCLUSIONS: The present work shows that FH+ have poor mood regulation and antisocial characteristics. The greater prevalence of ELA in FH+ persons indicates that life experience and FH+ work in tandem to result in risky patterns of alcohol and drug experimentation to elevate risk for alcoholism. Further studies of genetic and environmental contributions to alcoholism are called for.

Differences in stress reactivity may affect long-term health outcomes, but there is little information on how these differences arise. The stress axis is regulated by, in part, the endogenous opioid, beta-endorphin, acting on mu-opioid receptors. Persons carrying one or two copies of the G allele of the mu-opioid receptor gene (OPRM1 A118G) may have higher receptor binding for beta-endorphin compared with AA homozygotes that may contribute to individual differences in cortisol reactivity to stress, leading to a relative blunting of cortisol stress reactivity in G allele genotypes. We measured cortisol in 251 young adults (69 GA/GG vs 182 AA genotypes) exposed to mental arithmetic plus public speaking stress relative to a resting control day. Women had smaller cortisol responses than men (F=10.2, p=0.002), and women with GA or GG genotypes (N=39) had an absence of cortisol response relative to AA carriers (N=110) (F=18.4, p<0.0001). Male genotypes had no such difference in response (F=0.29). Cortisol response following mu-opioid receptor blockade using naltrexone in 119 of these subjects unmasked a greater tonic opioid inhibition of cortisol secretion in women (N=64), consistent with their blunted stress reactivity. Compared with men, women may have cortisol stress responses that are more heavily regulated by endogenous opioid mechanisms, and the OPRM1 GA/GG genotypes may affect females differentially relative to males. Diminished cortisol responses to stress may have consequences for health behaviors in women with GA/GG genotypes.

As the demographics of the U.S. population continues to change and become increasingly diverse, clinical psychologists will need to demonstrate their competence in providing culturally appropriate treatments to a wide variety of populations. This article summarizes a comprehensive content analysis of five of the leading scholarly journals in clinical psychology over a 17-year period (1980-1997). Results indicate that only 29.3% of the published articles in the clinical psychology literature included ethnic minority participants. Furthermore, only 5.4% of the articles actually focused specifically on ethnic minority populations. Thus, the clinical psychology literature does not contain adequate coverage of ethnically diverse populations in the U.S., despite their growing numbers. This content analysis provides the field with a baseline for future comparison to determine whether the field in general is responding to the needs of an increasingly diverse society, and to help gauge whether clinical psychologists have the scholarly resources available to assist them with becoming more culturally competent. Implications for the paucity of research and recommendations to ameliorate the problem are discussed.
