Understanding social network support, composition, and structure among cancer caregivers.

Objective: We examined the social network support, composition, and structure of pediatric cancer caregivers.

Methods: We used a self-report survey to collect egocentric social network data from 107 caregivers of pediatric cancer patients and calculated descriptive statistics to examine cancer-related support network composition, function, and structure. We then ran logistic regressions to examine the relationships between network characteristics and overall satisfaction with social support.

An initial investigation of using smartphone-enabled micro-temporal data collection to increase acceptability, feasibility, and validity of research on cancer caregiving.

Purpose: Smartphone-enabled micro-temporal data collection has potential to increase reliability, validity, and feasibility of participant-reported data and is a promising strategy for pediatric oncology supportive care and quality-of-life research. Given the demands of pediatric cancer caregiving, we sought to understand the feasibility and acceptability of smartphone data collection that included short surveys administered daily for 14 days via text message link.

Methods: We recruited pediatric cancer caregivers, whose children (ages 0-18 years) were on active treatment, to complete a 14-day daily survey study via smartphone.

Behavioral parenting skills as a novel target for improving medication adherence in young children: Feasibility and acceptability of the intervention.

In pediatric cancer care, medication non-adherence is a significant driver of avoidable suffering and death. There is a lack of interventions designed for families of young children, where patient medication refusal/avoidance is a common barrier to adherence. We developed the intervention which focuses on caregiver skills training to help young children take medicine calmly and without use of restraint techniques.

A preliminary test of a brief intervention to lessen young adults' cannabis use: Episode-level smartphone data highlights the role of protective behavioral strategies and exercise.

Brief interventions are increasingly being used to help young adults to moderate their cannabis use. We conducted a randomized clinical trial of a brief (4 weekly sessions), in-person intervention that included a smartphone application that reinforced the use of protective behavioral strategies (PBSs) to lessen cannabis use. Young adults ( = 37; 24 men) who regularly used cannabis were randomized to 2 intervention conditions rooted in cognitive-behavioral therapy (CBT) and motivational enhancement therapy (MET).

Effects of exercise on experimentally manipulated craving for cannabis: A preliminary study.

Cannabis is the most commonly used illicit drug in the United States, and craving for cannabis is related to cannabis use. Exercise has been demonstrated to reduce craving for substances. To examine the effects of exercise on cannabis craving, we conducted a 3-week within-subject crossover experiment.

The effects of perceived quality on behavioral economic demand for marijuana: A web-based experiment.

Background: Given the growing legalization of recreational marijuana use and related increase in its prevalence in the United States, it is important to understand marijuana's appeal. We used a behavioral economic (BE) approach to examine whether the reinforcing properties of marijuana, including "demand" for marijuana, varied as a function of its perceived quality.

Methods: Using an innovative, Web-based marijuana purchase task (MPT), a sample of 683 young-adult recreational marijuana users made hypothetical purchases of marijuana across three qualities (low, mid and high grade) at nine escalating prices per joint, ranging from $0/free to $20.

Analytical Problems and Suggestions in the Analysis of Behavioral Economic Demand Curves.

Behavioral economic demand curves (Hursh, Raslear, Shurtleff, Bauman, & Simmons, 1988) are innovative approaches to characterize the relationships between consumption of a substance and its price. In this article, we investigate common analytical issues in the use of behavioral economic demand curves, which can cause inconsistent interpretations of demand curves, and then we provide methodological suggestions to address those analytical issues. We first demonstrate that log transformation with different added values for handling zeros changes model parameter estimates dramatically.

A behavioral economic approach to assessing demand for marijuana.

In the United States, marijuana is the most commonly used illicit drug. Its prevalence is growing, particularly among young adults. Behavioral economic indices of the relative reinforcing efficacy (RRE) of substances have been used to examine the appeal of licit (e.

A beverage-specific measure of expectancies for malt liquor: development and initial testing.

Malt liquor (ML) is a unique, high alcohol content beverage marketed to encourage heavy drinking. We developed the Malt Liquor Expectancy Questionnaire (MLEQ), a beverage-specific measure of alcohol expectancies, and examined its association with typical weekly ML use, typical weekly alcohol use, and alcohol problems. Forty positive and 40 negative expectancy items were administered to a sample of 639 young adults who regularly consumed ML.

Validation of the revised Problems Assessment for Substance Using Psychiatric Patients.

This study assessed the factor structure, internal consistency, test-retest reliability, and construct validity of the Problems Assessment for Substance Using Psychiatric Patients (PASUPP; Carey, Roberts, Kivlahan, Carey, & Neal, 2004) with a sample of 278 men and women seeking outpatient dual-diagnosis treatment. All participants were diagnosed with a current AUD and schizophrenia and/or bipolar disorder. Initial confirmatory factor analysis did not support the 1-factor model for the 50-item measure found by Carey and colleagues.

Predicting post-treatment-initiation alcohol use among patients with severe mental illness and alcohol use disorders.

Few investigators studying alcohol abuse among individuals with a severe mental illness (SMI) have examined predictors of posttreatment alcohol outcomes. In the present study, a multivariate approach based on a theoretical model was used to study the relationship between psychosocial factors and post-treatment-initiation alcohol use. Predictors of alcohol use outcomes were examined in 278 individuals diagnosed with a current schizophrenia-spectrum or bipolar disorder and an alcohol use disorder (AUD).

Factors affecting agreement between severely mentally ill alcohol abusers' and collaterals' reports of alcohol and other substance abuse.

This study examined subject-collateral reports of alcohol use among a sample of 167 dually diagnosed individuals seeking outpatient treatment at a community mental health clinic. All subjects met Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) criteria for a schizophrenia-spectrum or bipolar disorder and for alcohol abuse or dependence.

Young-adult malt liquor drinkers: prediction of alcohol problems and marijuana use.

Malt liquor (ML) is a cheap, high alcohol content beverage that is marketed to appeal to young adults. Findings from the few published studies of ML use suggest that it may be associated with excessive drinking, alcohol problems, and the use of illicit drugs. The authors conducted separate hierarchical multiple regressions to examine the role of ML use and psychosocial variables (e.

Do individuals with a severe mental illness experience greater alcohol and drug-related problems? A test of the supersensitivity hypothesis.

The supersensitivity hypothesis posits that individuals with a severe mental illness (i.e., schizophrenia and bipolar disorder; SMI) are more likely to be diagnosed with a substance abuse as opposed to a substance dependence diagnosis, and experience greater negative consequences associated with substance use at lower levels of consumption, as compared with non-SMI substance abusers.

It does the job: Young adults discuss their malt liquor consumption.

Young adult men and women (N=53) who regularly consume malt liquor (i.e., 40 oz/week) participated in 10 semi-structured focus groups.
