Assessment of the 9-item Patient Health Questionnaire (PHQ-9) as a screen tool for symptoms of depression in community caregivers for adults with intellectual disabilities.
Half of community ID caregivers feel functionally impaired, and poor self-rated health is the clearest warning sign for depression.
01Research in Context
What this study did
Huang et al. (2014) asked community caregivers of adults with intellectual disability to fill out the 9-item Patient Health Questionnaire.
The team also asked about the caregiver’s own health and daily function.
They wanted to see if the PHQ-9 could flag caregiver depression in this group.
What they found
Almost half of the caregivers said they had trouble doing everyday tasks.
Only one thing clearly predicted serious depressive symptoms: caregivers who rated their own health as poor.
Other factors, like hours of care, did not add extra risk.
How this fits with other research
Chou et al. (2010) saw the same pattern in older female carers: two-thirds scored high for depression and poor health was the top link.
Hermans et al. (2010) warn that no depression screen for people with ID is fully proven yet, but the PHQ-9 is now one of the better choices for caregivers themselves.
Hutchins et al. (2020) add that caring for a child with ID also slashes caregiver quality of life, showing the strain starts early and lasts.
Why it matters
If you serve adults with ID, give the caregiver a PHQ-9 while you assess the client.
When the caregiver says, “My health is poor,” flag them for follow-up or respite.
A five-minute screen can catch the people most at risk of burnout and keep the whole home situation safer.

03Original abstract
The study aim was to determine the extent and determinants of reporting depressive symptoms in caregivers for persons with intellectual disabilities based on assessment of the 9-item Patient Health Questionnaire (PHQ-9). A cross-sectional study was conducted, recruiting 455 caregivers for adults with ID who were providing care in community residences, with complete PHQ-9 data being analyzed. The results indicated that the mean of each item scored on the PHQ-9 varied from 0.3 (Q9) to 1.1 (Q4). For two items (Q3 - "sleeping difficulties" and Q4 - "fatigue"), the respondents reported occurrence during several days in the previous two weeks. However, after scrutinizing the distribution of each item in the PHQ-9, 3.3-14.5% respondents reported that each item happened nearly every day, and 4.0-17.8% expressed that each happened more than half of the days in the previous two weeks. With respect to difficulties examined on the PHQ, 47% of cases expressed that it was somewhat difficult, 8.2% expressed that it was very difficult, and 4.5% felt that it was extremely difficult to work, care for things at home, or get along with others. Finally, a logistic regression model revealed that only one factor of self-perceived health status (fair/poor vs. excellent/very good, OR=7.519, 95% CI=3.03-18.68, p<0.001) exhibited a statistically significant correlation with depressive symptom occurrence (PHQ-9 score ≥ 10) among the caregivers. The study highlights the need to strengthen appropriate health initiatives for monitoring mental health status and to provide necessary services for community caregivers for adults with ID.
