This study aimed to identify whether nonparental preschool childcare was associated with adolescent mental health outcomes as measured by the strengths and difficulties questionnaire (SDQ).
This study was a secondary analysis of data from the Croydon Assessment of Learning Study. From a general population sample of 2,726 adolescents tested for cognitive ability, additional data were collected from a stratified sub-sample of 197 subjects. A semi-structured interview asked parents about preschool childcare and early development concerns. Parent and teacher SDQ and IQ data were collected. Complete data were available from 167 subjects. Using nonparental preschool childcare as the 'treatment' effect and parental childcare as the 'control', propensity score matching analyses were used to analyse the effect of nonparental childcare on adolescent SDQ outcomes.
Nonparental childcare was reported by 49% of the sample and was not significantly associated with conduct, emotional, peer or prosocial SDQ subscales, but was found to have a significant average treatment effect on symptoms of attention/hyperactivity, on average raising the symptom subscale score by 1.8 (95% confidence interval 0.12-3.65). The propensity score analysis ensures the results could not be explained by the available measures that influenced receiving nonparental care. Increased time spent in nonparental childcare was associated with greater attention/hyperactivity symptoms.
Nonparental preschool care showed little association with generalized psychopathology but may be associated with hyperactivity and inattention problems. Replication of these findings in prospective studies is required.
本研究旨在确定非父母学前儿童保育是否与青少年心理健康结果相关，这些结果是通过《长处和困难问卷》（SDQ）来衡量的。
本研究是对克罗伊登学习评估研究数据的二次分析。从接受认知能力测试的 2726 名青少年的一般人群样本中，从分层的子样本中收集了 197 名受试者的额外数据。半结构化访谈询问了父母有关学前儿童保育和早期发展问题的情况。收集了父母和教师的 SDQ 和智商数据。共有 167 名受试者提供了完整的数据。将非父母学前儿童保育作为“治疗”效果，将父母保育作为“对照”，使用倾向评分匹配分析来分析非父母保育对青少年 SDQ 结果的影响。
该样本中 49%的人报告了非父母保育，非父母保育与行为、情感、同伴或亲社会 SDQ 子量表均无显著相关性，但与注意力/多动症状存在显著的平均治疗效果，平均使症状子量表评分提高了 1.8（95%置信区间 0.12-3.65）。倾向评分分析确保了结果不能用影响接受非父母照顾的可用措施来解释。非父母保育时间的增加与注意力/多动症状的增加有关。
非父母学前儿童保育与一般精神病理学的相关性较小，但可能与多动和注意力不集中问题有关。需要在前瞻性研究中复制这些发现。
