Retrospective Recall of Marijuana Use Patterns Following the COVID-19 Outbreak Vary as a Function of User Type Among Adolescents in Washington State.

Marijuana use in middle and late adolescence is a significant public health concern given that an earlier age of onset is prospectively associated with numerous marijuana misuse outcomes. The outbreak of COVID-19 resulted in stay-at-home orders and social distancing guidelines across the United States yet the impact of these orders on adolescent marijuana use is unknown in the U.S. The aims of this study were to examine adolescents' recall of changes in marijuana use patterns following the COVID-19 outbreak as a function of one's typical levels of use, and to qualitatively assess reasons for perceived change. A screening survey for a larger study was completed by 156 adolescents (ages 15-18, 78% male) after the stay-at-home order was put in place in Washington state in March 2020. The cross-sectional survey included self-reported demographic information, marijuana use, and retrospective recall of changes to marijuana use following the state's stay-at-home order. Initial findings did not reveal any pattern of change that described the entire sample, however adolescents' recall of changes in use significantly varied as a function of typical use such that moderate/heavy users had higher odds of reporting maintained (5.04 times higher) or increased use (3.07 times higher) compared to irregular/light marijuana users. Primary reasons for decreasing use included decreased availability and socialization. Primary reasons for increasing use included more free time and coping with stress and anxiety. The findings suggest that pandemic-related changes in marijuana use are not consistent across adolescents and that moderate and heavy users may be at increased risk of marijuana misuse under pandemic conditions.

Understanding perceived usefulness and actual use of protective behavioral strategies: The role of perceived norms for the reasons that young adult drinkers use protective behavioral strategies.

INTRODUCTION: The current study examines the norms-behavior link by investigating a novel cognition for protective behavioral strategies (PBS)-descriptive and injunctive norms for close friends' reasons to use PBS (e.g., limit drinking, reduce consequences)-in relation to one's own perception of usefulness and personal use of PBS. Further, we tested whether the association between perceived norms for reasons to use PBS and personal PBS use was mediated by perceived usefulness of PBS. METHODS: College student drinkers ages 18-24 [N = 301; 53% female, 69% White, mean age = 20.16 years (SD = 1.54)] were recruited for a larger study. Eligible students reported alcohol use 2+ days a week and 1+ occasions of heavy episodic drinking in the last two weeks. Linear regression tested whether descriptive and injunctive norms for reasons to use PBS were associated with perceived usefulness and personal use of PBS; path analysis was used to test mediation. All analyses were conducted by PBS subscale (limiting/stopping, serious harm reduction, manner of drinking). RESULTS: Descriptive norms for reasons to use PBS (i.e., perceptions that close friends use PBS to reduce drinking/consequences) were positively associated with perceived usefulness and personal PBS use for limiting/stopping and to some extent manner of drinking. For each subscale, the association between descriptive norms for reasons to use PBS and personal PBS use was mediated by perceived usefulness of PBS. Results were not significant for injunctive norms. CONCLUSIONS: Findings suggest descriptive norms, rather than injunctive norms, for close friends' reasons to use PBS, may be relevant for inclusion in brief interventions.

A single-case quasi-experimental design of functional analytic psychotherapy for substance abuse / Um delineamento quase-experimental de caso único da psicoterapia analítica funcional para abuso de substâncias / Un diseño de caso único cuasi experimental de psicoterapia analítica funcional para abuso de sustancias

This study evaluated the effectiveness of Functional Analytic Psychotherapy (FAP) on clinically relevant behaviors (CRBs) in the context of substance abuse/chemical de pendence and identifying the therapeutic components of change. The Functional Analytic Psychotherapy Rating Scale (FAPRS) was used to categorize therapist and client behaviors, and Timeline Followback was used to record drug abuse. Two participants were treated in a single case A/A + B quasi-experimental design, in which A = analytical-behavioral therapy and A + B = FAP. The results showed that with the introduction of FAP, specifically the therapist's contingent responding to the participant's progress, there was a decrease in the use of substances after three months for both participants. The participant who spent more time in psychotherapy experienced greater benefits at follow-up and a larger reduction in drug use. We concluded that FAP altered CRBs by positively reinforcing progress in-session and was significantly correlated with improvement out-of-session.

O objetivo da pesquisa foi avaliar o efeito da Psicoterapia Analítica Funcional (FAP) sobre os comportamentos clinicamente relevantes (CRBs) e abuso de substâncias de dependentes químicos e identificar os componentes terapêuticos de mudança. Foram utilizados os instrumentos Functional Analytic Psychotherapy Rating Scale para categorização de comportamentos do terapeuta e cliente e Timeline Followback para registrar o abuso de drogas. Dois participantes foram atendidos em um delineamento quase-experimental de caso único A/A+B, onde A = Terapia Analítico-Comportamental e A+B = FAP. Os resultados indicaram que a introdução da FAP, em especial o responder contingente do terapeuta, acompanhou os progressos e houve melhora no consumo de substâncias após 3 meses para ambos. O participante que se manteve mais tempo em psicoterapia obteve maior benefício no follow-up e no consumo de drogas. Concluiu-se que a FAP alterou CRBs reforçando positivamente progressos em sessão e que isto provavelmente se correlacionou com melhoras extrassessão.

El objetivo fue evaluar el efecto de la Psicoterapia Analítica Funcional (FAP) en los comportamientos clínicamente relevantes (clinically relevant behaviors - CRBs) e el abuso de sustancias de dependientes químicos, e identificar los componentes terapéuticos de cambio. Se utilizaron Functional Analytic Psychotherapy Rating Scale, para clasificar los comportamientos del terapeuta y del cliente, y timeline followback, para registrar el abuso. Dos participantes fueron evaluados a través de un diseño cuasiexperimental de caso único A/A + B, donde A = terapia analítico-comportamental y A + B = FAP. Los resultados indicaron que la implementación de la respuesta contingente del terapeuta llevó a cambios en las CRBs y mejorías en el consumo de sustancias en los dos participantes después de tres meses de intervención. El participante que se mantuvo más tiempo en psicoterapia obtuvo mayor beneficio durante el seguimiento. Se concluye que FAP modificó las CRBs a través del reforzamiento positivo en sesión, lo que se relacionó con las mejoras fuera de sesión.

Alcohol-specific social comparison as a moderator of the norms-behavior association for young adult alcohol use.

Research has indicated that individuals high in social comparison orientation (SCO) are more influenced by the behavior and perceived norms of others. However, despite research indicating that behavior is more closely influenced by and modeled on more socially proximal reference groups, most social comparison research to date has utilized global measures of social comparison. As such, research has not examined whether domain-specific (i.e. alcohol-specific social comparisons) and their relation with norms are more predictive of alcohol-related outcomes than global comparisons. As such, the present study aimed to determine whether the previously found relationships between global SCO, descriptive drinking norms and their interaction are still significant when accounting for alcohol-specific SCO and its interaction with descriptive norms in the prediction of drinking willingness and behavior. Results from 355 young adults age 18-20 indicated that the association of alcohol-specific SCO and its interaction with descriptive norms for drinking predicts alcohol-related outcomes (drinking willingness and alcohol consumption), but not alcohol-related negative consequences above and beyond global SCO. Thus, alcohol-specific SCO may be of particular importance when determining for whom normative based preventive interventions may be the most efficacious.
