Some effects of teenagers' part‐time employment: The quantity and quality of work make the difference
研究了高中生兼职工作的数量和质量与学业表现（逃课、作业、成绩）及个人功能（自尊、时间利用）的关系，发现长时间兼职有负面影响，但工作质量高时这种影响减弱。
Abstract We investigated the associations of the quantity and quality of part‐time employment with the school performance (amount of class cutting, homework, and average grades) and personal functioning (self‐esteem and time use) of high‐school students. Two hypotheses were tested: (a) working long hours would be associated with detrimental effects, but (b) the quality of employment would moderate these effects, such that employment quantity would be associated with detrimental effects only for low quality jobs. Data from 563 high school students ( n = 233 in part‐time employment) provided support for the hypotheses. Conceptual, practical and policy ramifications of these findings are considered.
