{"doi":"10.1093/jpepsy/jsaa097","title":"Associations Between Peer Use, Costs and Benefits, Self-Efficacy, and Adolescent E-cigarette Use","abstract":"OBJECTIVE: Prior research identified peer use as a salient risk factor of adolescent electronic cigarette (e-cigarette) use, but has not expanded on the mechanisms of this association. METHODS: Participants were 562 adolescents recruited from rural and suburban public high schools and an adolescent medicine clinic in the mid-Atlantic United States. Participants completed a packet of questionnaires that assessed demographics, substance use, expectations about the consequences of e-cigarette use, and perceptions of their own self-efficacy to resist using e-cigarettes. We estimated a series of mediation models using the MODEL INDIRECT command in MPLUS statistical software. In all models, significance of indirect effects from peer e-cigarette use to self-reported e-cigarette use were tested via two variables: (a) expected costs, (b) benefits of e-cigarette use, and (c) the perceived self-efficacy of the individual to refrain from e-cigarette use. RESULTS: Adolescents with more peers using e-cigarettes were more likely to have ever used an e-cigarette and perceived greater benefits and fewer costs, which was associated with a reduced self-efficacy to refrain from e-cigarette smoking (Model 1). Those with more peers using e-cigarettes were more likely to be currently using e-cigarettes themselves because they perceived greater benefits and fewer costs, which was associated with a reduced self-efficacy to refrain from e-cigarette smoking (Model 2). CONCLUSION: Peer use, self-efficacy to resist use, and expectations of cost and benefits of e-cigarette use should be considered as possible targets when devising tailored interventions and policies to prevent or reduce negative health consequences of long-term e-cigarette use.","journal":"Journal of Pediatric Psychology","year":2020,"id":98100,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":32,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.946,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":484590,"name":"Desireé N Williford","orcid":"0000-0003-1763-5507","position":1,"is_corresponding":false},{"id":484591,"name":"Nicholas A.
