The aim of this exploratory study was to identify developmental patterns of adolescent concurrent alcohol, cannabis, and other illicit drug use and their preadolescent individual, familial, and social risk factors in a population-representative cohort from the province of Quebec, Canada ( = 1,593; 48.4% male). Age 12-17 years self-reports of alcohol, cannabis, and other illicit drug use were collected. Latent growth modeling was used to analyze developmental patterns of single- or polysubstance use (SU/PSU), and multinomial regression examined their association with risk factors assessed at age 10-12 years. Five developmental patterns were revealed, including nonusers (12.8% sample) and four classes reflecting different levels of SU/PSU (5.8%-37.5%), varying in severity based on onset, frequency, and type of substances used. Boys and girls were similarly represented throughout SU/PSU patterns. In comparisons with nonusers, several preadolescent risk factors were associated with increasing severity of SU/PSU. Possibly indexing fearlessness/disinhibition, low internalizing symptoms were common to all adolescent users. An earlier onset of substance use and increasing use of substances throughout adolescence were linked with having deviant peers for all user classes but later-onset users. Preadolescents manifesting externalizing problems and exposed to family adversity in addition to the above risk factors showed the earliest onset and most frequent adolescent SU/PSU, especially those also exposed to less appropriate parenting. Consistent with the developmental model of substance use, the nature, number, and severity of preadolescent risk factors distinguished between the type and severity of SU/PSU patterns in adolescence and call for a consistent strategy of universal, selective, and indicated preventive interventions.

这项探索性研究的目的是，在加拿大魁北克省一个具有人口代表性的队列中（ = 1,593；48.4%为男性），确定青少年同时使用酒精、大麻和其他非法药物的发展模式及其青春期前的个人、家庭和社会风险因素。收集了12至17岁青少年关于酒精、大麻和其他非法药物使用的自我报告。采用潜在增长模型分析单一物质或多种物质使用（SU/PSU）的发展模式，并通过多项回归研究其与10至12岁时评估的风险因素之间的关联。研究揭示了五种发展模式，包括非使用者（占样本的12.8%）和四类反映不同水平SU/PSU的模式（5.8%-37.5%），根据开始使用的时间、频率和使用的物质类型，严重程度各不相同。在整个SU/PSU模式中，男孩和女孩的比例相似。与非使用者相比，一些青春期前的风险因素与SU/PSU严重程度的增加有关。低内化症状可能表明无畏/抑制不足，这在所有青少年使用者中都很常见。除了后期开始使用物质的使用者外，所有使用者类别中，物质使用开始时间较早以及整个青春期物质使用量增加都与有偏差同伴有关。除上述风险因素外，表现出外化问题并经历家庭逆境的青春期前儿童，其青少年SU/PSU开始时间最早且频率最高，尤其是那些还受到不太恰当养育方式影响的儿童。与物质使用的发展模型一致，青春期前风险因素的性质、数量和严重程度区分了青少年SU/PSU模式的类型和严重程度，这需要采取一致的策略，包括普遍、选择性和针对性的预防干预措施。（PsycInfo数据库记录（c）2024美国心理学会，保留所有权利）
