Preference between predictable and unpredictable administrations of carbon dioxide-enriched air
Predictability of panic attacks has been identified as an important factor in the development, maintenance, and treatment of panic disorder. Although animal studies typically have found a preference for signaled (predictable) over unsignaled (unpredictable) aversive events, results with human participants have been less clear. Because preference for predictability has a wide range of clinical implications, we examined human preference for predictability in a biological challenge paradigm. Further, we examined the differential effects of predictability as a function of anxiety sensitivity and gender. In general, females showed a significantly greater preference for predictability compared to males, as did high anxious participants compared to their low anxious counterparts. Specifically, high anxious females showed the greatest preference for predictability, high anxious males and low anxious females showed moderate preference for predictability, and low anxious males were indifferent. Although the results suggest the necessity of considering individual difference variables such as gender and anxiety sensitivity, support is provided for the use of prediction testing and other strategies to enhance an individual\u27s prediction of panic attacks in the treatment of panic disorder

Brief Behavioural Activation (Brief BA) for adolescent depression: a pilot study
Background: Depression in adolescence is a common and serious mental health problem. In the UK, access to evidence based psychological treatments is limited and training and employing therapists to deliver these is expensive. Brief Behavioral Activation for the Treatment of Depression (BATD) has great potential for use with adolescents and to be delivered by a range of healthcare professionals, but there is limited empirical investigation with this group.
Aims: To adapt BATD for depressed adolescents (Brief BA) and conduct a pilot study to assess feasibility, acceptability and clinical effectiveness.
Methods: Twenty depressed adolescents referred to the local NHS Child and Adolescent Mental Health service (CAMHs) were offered 8 sessions of Brief BA followed by a review around one month later. Self- and parent- reported Routine Outcome Measures (ROMs) were collected at every session.
Results: Nineteen of the 20 young people fully engaged with the treatment and all reported finding some aspect of Brief BA helpful. Thirteen (65%) required no further psychological intervention following Brief BA, and both young people and parents reported high levels of acceptability and satisfaction with the approach. The pre-post effect size of Brief BA treatment was large.
Conclusions: Brief BA is a promising innovation in the treatment of adolescent depression. This approach requires further evaluation to establish effectiveness and cost effectiveness compared with existing evidence-based treatments for adolescent depression. Other questions concern the effectiveness of delivery in other settings and when delivered by a range of professionals
Examining risk for frequent cocaine use: Focus on an African American treatment population
BACKGROUND:
Cocaine use and its consequences are disproportionately higher and more severe among African Americans compared to other ethnic/racial groups.
OBJECTIVES:
The aims of this study were to examine a risk model specific for African American users and assess whether risk varies as a function of sex.
METHODS:
270 African American adults in a residential drug treatment facility completed measurements assessing first and past year crack/cocaine use frequency, childhood trauma, and stress reactivity. Multiple linear regression analysis was used to examine the unique effect of each predictor variable on past year crack/cocaine frequency. Sex was included as a moderator variable in the regression analysis.
RESULTS:
All predictor variables were positively correlated with past year crack/cocaine use. However, sex differences were also observed: females reported higher rates of childhood emotional abuse, childhood sexual abuse, and stress reactivity-as well as past year crack use and cocaine use-than males. Regression analyses were performed with sex, first year use, and stress reactivity emerging as the only significant predictors for frequency of crack and cocaine use among all study participants. Moreover, sex differences were observed in the influence of first year crack use frequency on past year crack use frequency, such that the effect was stronger for males than for females. Conclusion/Importance: This study offers a clearer understanding of the risk factors for crack and cocaine abuse specific to African Americans, as well as sex specific pathways to risk, providing useful implications for future prevention and treatment efforts
The Balloon Analog Insurance Task (BAIT): A Behavioral Measure of Protective Risk Management
Prior methods used to assess individual differences related to risk have not focused on an important component of risk management: how willing individuals are to pay for or take actions to insure what they already have. It is not clear whether this type of protective risk management taps into the same individual differences as does risk taking propensity measured by existing risk taking tasks. We developed a novel task to assess protective risk management, the Balloon Analog Insurance Task (BAIT), which is modeled after the Balloon Analog Risk Task (BART). In the BAIT, individuals are forced to decide how much money they are willing to pay in order to insure a specific fraction of their prior winnings given changing but imprecise levels of risk of monetary loss. Participants completed the BART and BAIT for real monetary rewards, and completed six self report questionnaires. The amount of insurance purchased on the BAIT was positively correlated with scores on the Intolerance of Uncertainty Scale and on the Checking scale of the revised Obsessive Compulsive Inventory. Conversely, the amount of insurance purchased was negatively correlated with scores on the Domain Specific Risk Taking Questionnaire, and on the Psychopathic Personality Inventory (PPI). Furthermore, relationships between insurance purchased and these scales remained significant after controlling for the BART in linear regression analyses, and the BART was only a significant predictor for measures on one scale - the PPI. Our results reveal that behavior on the BAIT taps into a number of individual differences that are not related to behavior on another measure of risk taking. We propose that the BAIT may provide a useful complement to the BART in the assessment of risk management style
The efficacy of a behavioral activation intervention among depressed US Latinos with limited English language proficiency: study protocol for a randomized controlled trial
Major depressive disorder is highly prevalent among Latinos with limited English language proficiency in the United States. Although major depressive disorder is highly treatable, barriers to depression treatment have historically prevented Latinos with limited English language proficiency from accessing effective interventions. The project seeks to evaluate the efficacy of behavioral activation treatment for depression, an empirically supported treatment for depression, as an intervention that may address some of the disparities surrounding the receipt of efficacious mental health care for this population. Following a pilot study of behavioral activation treatment for depression with 10 participants which yielded very promising results, the current study is a randomized control trial testing behavioral activation treatment for depression versus a supportive counseling treatment for depression. We are in the process of recruiting 60 Latinos with limited English language proficiency meeting criteria for major depressive disorder according to the Diagnostic and Statistical Manual of Mental Disorders 4th and 5th Edition for participation in a single-center efficacy trial. Participants are randomized to receive 10 sessions of behavioral activation treatment for depression (n = 30) or 10 sessions of supportive counseling (n = 30). Assessments occur prior to each session and at 1 month after completing treatment. Intervention targets include depressive symptomatology and the proposed mechanisms of behavioral activation treatment for depression: activity level and environmental reward. We will also examine other factors related to treatment outcome such as treatment adherence, treatment satisfaction, and therapeutic alliance. This randomized controlled trial will allow us to determine the efficacy of behavioral activation treatment for depression in a fast-growing, yet highly underserved population in US mental health services. The study is also among the first to examine the effect of the proposed mechanisms of change of behavioral activation treatment for depression (that is, activity level and environmental reward) on depression over time. To our knowledge, this is the first randomized controlled trial to compare an empirical-supported treatment to a control supportive counseling condition in a sample of depressed, Spanish-speaking Latinos in the United States.https://doi.org/10.1186/1745-6215-15-23
Altered interaction with environmental reinforcers in major depressive disorder: Relationship to anhedonia
Anhedonia—defined as loss of interest or pleasure—is one of two core symptoms of major depressive disorder (MDD). Anhedonia may involve decreased enjoyment of potentially rewarding activities and decreased motivation to engage in such activities. Increased engagement with reinforcers—activities with the potential to be positive experiences—is a frequent target of cognitive-behavioral therapies. Nevertheless, how environmental reinforcers are perceived, and how decisions to approach or avoid them are made by individuals with MDD, is largely unknown. We developed an experimental Behavioral Approach Motivation Paradigm to study how activities are evaluated and approached in MDD. Twenty-one MDD participants and 23 healthy controls performed an experimental task that rated activity words for their hedonic value, then engaged in an approach-avoidance joystick task with each individual’s unique set of ‘liked’ and ‘disliked’ activity words. A negative correlation was observed between anhedonia and the number of ‘liked’ activities across participants. No significant difference between approach and avoidance behavior was found in direct comparisons between healthy controls and MDD participants; however, weaker avoidance and greater approach toward ‘disliked’ activities was found in MDD participants. This suggests negative bias in selecting environmental opportunities, potentially further compromising access to hedonic experiences in MDD

Greater use of appearance-focused social media, such as Instagram, is associated with increased body dissatisfaction and eating disorder (ED) symptoms; however, questions remain about the mechanism connecting social media use to disordered-eating behaviors (DEBs). The proposed study evaluates how and for whom exposure to fitspiration or thinspiration on Instagram is associated with DEBs.
Methods
We will evaluate a hypothesized pathway from Instagram use to disordered-eating mediated by negative affect. We will test how individual differences in internalized weight stigma, trait self-esteem, and trait self-comparison moderate the pathway from social media use to negative affect. We will recruit 175 undergraduate women who report engaging in DEBs on average at least once per week over the past 3 months. Participants will complete a 7-day ecological momentary assessment protocol, during which they will report their Instagram use, affect, and engagement in DEBs.
Results
Multi-level modeling will be used to assess moderated mediation. Results from this study will provide increased specificity about how Instagram usage is linked to eating pathology and who may be most vulnerable to experiencing distress.
Discussion
Information about negative affect from Instagram and engagement in DEBs could contribute to the development of Just-In-Time Interventions for problematic social media use
