Beck's cognitive theory and the response style theory of depression in adolescents with and without mild to borderline intellectual disability.
Standard depression thinking patterns apply to teens with mild-borderline ID, but underestimated coping skill is the extra lever to treat.
01Research in Context
What this study did
The team tested two big ideas about teen depression. One idea says sad thoughts cause low mood. The other says brooding and giving up keep the blues alive.
They asked teens with and without mild-borderline ID the same questions. Then they checked which answers best predicted who felt depressed.
What they found
Both groups showed the same thinking and response-style patterns. Negative thoughts and rumbling on problems were tied to feeling down in every teen.
Only one thing stood out for the ID group. Teens with MBID greatly under-rated their own coping skill, and that gap gave extra power in predicting depression.
How this fits with other research
Dai et al. (2023) already showed CBT can cut anxiety in mild ID when you add visuals and small groups. Laposa et al. (2017) now give the cognitive map that explains why those tweaks work.
van Timmeren et al. (2016) warned that problem behaviours in adults with ID often look like depression but really show emotional dysregulation. The new data say teens with MBID do show true cognitive depression signs, so you can trust Beck-based tools here.
Orío-Aparicio et al. (2025) report wide adaptive-skill gaps in borderline IQ clients. Underestimated coping in Laposa et al. (2017) lines up with that picture and points to where intervention should aim.
Why it matters
You can keep using standard CBT mood logs and rumination scales with teens who have mild-borderline ID. Just add one extra check: ask "How well could you handle this problem?" If their rating is far below what you observe, teach coping micro-steps and celebrate small wins. This single move targets the cognition that most predicts depression in this group.

03Original abstract
AIM: This study tests the validity of Beck's cognitive theory and Nolen-Hoeksema's response style theory of depression in adolescents with and without MBID. METHODS: The relationship between negative cognitive errors (Beck), response styles (Nolen-Hoeksema) and depressive symptoms was examined in 135 adolescents using linear regression. RESULTS: The cognitive error 'underestimation of the ability to cope' was more prevalent among adolescents with MBID than among adolescents with average intelligence. This was the only negative cognitive error that predicted depressive symptoms. There were no differences between groups in the prevalence of the three response styles. In line with the theory, ruminating was positively and problem-solving was negatively related to depressive symptoms. Distractive response styles were not related to depressive symptoms. The relationship between response styles, cognitive errors and depressive symptoms were similar for both groups. CONCLUSION: The main premises of both theories of depression are equally applicable to adolescents with and without MBID. The cognitive error 'Underestimation of the ability to cope' poses a specific risk factor for developing a depression for adolescents with MBID and requires special attention in treatment and prevention of depression. WHAT THIS PAPER ADDS?: Despite the high prevalence of depression among adolescents with MBID, little is known about the etiology and cognitive processes that play a role in the development of depression in this group. The current paper fills this gap in research by examining the core tenets of two important theories on the etiology of depression (Beck's cognitive theory and Nolen-Hoeksema's response style theory) in a clinical sample of adolescents with and without MBID. This paper demonstrated that the theories are equally applicable to adolescents with MBID, as to adolescents with average intellectual ability. However, the cognitive bias 'underestimation of the ability to cope' was the only cognitive error related to depressive symptoms, and was much more prevalent among adolescents with MBID than among adolescents with average intellectual ability. This suggests that underestimating one's coping skills may be a unique risk factor for depression among adolescents with MBID. This knowledge is important in understanding the causes and perpetuating mechanisms of depression in adolescents with MBID, and for the development of prevention- and treatment programs for adolescents with MBID.
