背　景:瞭解青少年性認知對性溝通之影響，有利於設計符合青少年需求之性健康促進活動。目　的:本研究目的旨於瞭解青少年性溝通，以及性認知與性溝通之關係，並找出性溝通之有效預測因子。方　法:採橫斷式研究法及方便取樣，針對台灣中部某醫專青少年共900位進行調查，有效問卷748份，回收率83.1%。研究問卷包含：個人變項、性自我概念量表、性風險認知問卷、性自我效能量表、以及性溝通量表。所收集之資料使用描述性統計、皮爾遜積差相關、以及多元迴歸進行分析。結　果:(一)青少年與父母性溝通頻率呈中等程度（Mean = 2.52 ± 1.24）。(二)性認知因子（包含性自我概念、性風險認知、性自我效能）與性溝通呈正相關。(三)青少年個人變項（有異性朋友、滿意異性朋友關係、以及有異性朋友時間的長短）及性認知因子是性溝通之有效預測因子，其解釋變異量達62.0%。結　論／實務應用:建議社會應多鼓勵親子間的性溝通，健康專業人員於發展「性健康教育課程」時，應先瞭解青少年性溝通議題；增加青少年性認知可能有助於提升其與父母的性溝通頻率。

Background: Further understanding the relationship between
sexual cognition and sexual communication in adolescents
may facilitate sexual health promotion in this population.
Purpose: This study was designed to investigate associations between sexual cognitive variables and sexual communication in adolescents.
Methods: This study used a cross-sectional research design with conventional sampling. Data were collected from one medical college in central Taiwan. A total of 900 questionnaires were dispatched, with 748 copies returned, giving a response rate of 83.1%. Structural questionnaires were designed to collect demographic data, sexual self-concept inventory, sexual risk cognition, sexual self-efficacy, and sexual communication scale. This study applied statistical methods, including descriptive statistics, Pearson product-moment correlation, and multiple regression analysis.Results: Major findings revealed that (a) adolescents talked about sexual activity and sexual issues with their parents at a moderate level (mean = 2.52, SD = 1.24), (b) all sexual
cognitive variables (sexual self-concept, sexual risk cognitions,
and sexual self-efficacy) correlated positively with sexual communication, and (c) predictors of sexual communication were supported by demographic data (having heterosexual friends, satisfaction with heterosexual friends, and duration of relationships with heterosexual friends) and sexual cognitive variables, which accounted for 62.0% of variance.Conclusions/Implications for Practice: Study results can
contribute to the development of safe sexual health programs
and improve healthcare provider knowledge of sexual communication among adolescents. More sexual communication between adolescents and their parents is encouraged.Moreover, sexual health programs must give increased focus on the issue of adolescent sexual cognition to help encourage increased discussion between adolescents and their
parents regarding sexual activity and issues.
