Study 1 evaluated whether pregnancy is a stressful life event for teenagers and is associated with depression for teenagers with a pessimistic attributional style but not for those with an optimistic attributional style. Study 2 replicated unexpected findings from study 1. Study 3 evaluated whether pregnant teenagers with a pessimistic attributional style will be more depressed after childbirth than optimistic pregnant teenagers.
In study 1, 122 pregnant and 96 nonpregnant teenagers completed questionnaires assessing depression and attributional style. In study 2, 43 pregnant teenagers and 49 nonpregnant teenagers completed the same questionnaires. In study 3, subjects from studies 1 and 2 were contacted by mail and asked to complete the same questionnaires; 63 (38%) did so.
In studies 1 and 2, pregnant teenagers with a pessimistic attributional style were less depressed than those with an optimistic attributional style and the nonpregnant group. In study 3, pessimistic teenagers experienced a higher level of depression than nonpessimistic adolescents following childbirth.
Pregnancy may serve to protect pessimistic teenagers from experiencing depression. The subsequent demands of motherhood may remove any protection from depression afforded by the pregnancy. The experience of depression being relieved by another pregnancy may be a previously unidentified risk factor for repeated pregnancies in teenagers.
研究1评估怀孕对青少年而言是否属于压力性生活事件,以及怀孕是否与具有悲观归因风格的青少年的抑郁相关,但与具有乐观归因风格的青少年的抑郁无关。研究2重复了研究1中意外的发现。研究3评估具有悲观归因风格的怀孕青少年在产后是否会比乐观的怀孕青少年更加抑郁。
在研究1中,122名怀孕青少年和96名未怀孕青少年完成了评估抑郁和归因风格的问卷。在研究2中,43名怀孕青少年和49名未怀孕青少年完成了相同的问卷。在研究3中,通过邮件联系了研究1和研究2中的受试者,并要求他们完成相同的问卷;63人(38%)照做了。
在研究1和研究2中,具有悲观归因风格的怀孕青少年比具有乐观归因风格的青少年以及未怀孕组的青少年抑郁程度更低。在研究3中,悲观的青少年在产后比非悲观的青少年经历了更高程度的抑郁。
怀孕可能有助于保护悲观的青少年免于抑郁。为人母随后带来的要求可能会消除怀孕所给予的对抑郁的任何保护。抑郁因再次怀孕而缓解的经历可能是青少年重复怀孕的一个先前未被识别的风险因素。
