Parents of children with developmental disabilities (DD) consistently report significant psychological distress, a vulnerability amplified during the COVID-19 pandemic due to intensified caregiving demands and reduced access to formal supports. Scalable e-health interventions offer a promising alternative, yet programs specifically targeting the mental wellbeing of this parent population remain limited. This study aimed to examine the impact of the 90SecondParent Wellbeing e-health intervention on psychological wellbeing, parental wellbeing, and symptoms of depression and anxiety among parents of children with developmental disabilities. A two-arm randomized controlled trial of primary caregivers of children with developmental disabilities was conducted with a wait-list control group. The intervention consisted of 36 weekly health letters (the 90SecondParent Wellbeing program) that addressed child behaviour management, support strategies, and positive psychology principles. Outcomes, including psychological wellbeing (PWBS), parental wellbeing (PWS), depression (PHQ-9), and anxiety (GAD-7), were assessed across three time points ( baseline, immediately after intervention, and 1 month post-intervention (follow-up)).

Psychological wellbeing (PWBS)
The Psychological Wellbeing (PWBS) measure assesses six aspects of wellbeing: autonomy, environmental mastery, personal growth, positive relations with others, purpose in life, and self-acceptance. Items are rated on a 7-point Likert-type scale ranging from 1 (Strongly agree) to 7 (Strongly disagree). Higher scores indicate greater wellbeing. The PWBS was measured at baseline, post-assessment, and follow-up.Total scores range from 18 to 126, with higher scores indicating greater psychological wellbeing.
Time frame: Baseline, Immediately after intervention (18 weeks), 1 month post-intervention
Parent Wellbeing
Parent wellbeing was measured using the Parent Well-being Scale. This scale was completed at baseline, immediately after intervention, and at 1-month post-intervention. The Parent Well-being Scale is an 8-item measure that assesses parents' feelings when caring for their child with developmental disabilities. Items are expressed as polar opposites in two columns, separated by ten boxes from 1 to 10. For example, a score of 1 for the stress item means the parent feels very stressed, and a score of 10 means the parent is very relaxed and not stressed at all. Total scores range from 8 to 80, with higher scores indicating greater parent wellbeing and satisfaction
Time frame: Baseline, Immediately after intervention (18 weeks), 1 month post-intervention
Depressive symptoms
Patient Health Questionnaire-9 (PHQ-9) was administrated to assess current symptoms of depression. This scale was completed at baseline, immediately after intervention, and at 1-month post-intervention. PHQ-9 is a self-report measure that asked participants to report how often they have been bothered by a series of depression symptoms over the prior two weeks. PHQ-9 items are summed to create a total score. Total scores range from 0 to 27, with higher scores indicating greater depression severity.
Time frame: Baseline, Immediately after intervention (18 weeks), 1 month post-intervention
Generalized Anxiety Symptoms
Generalized Anxiety Disorder-7 (GAD-7) was used to measure current anxiety symptoms. This scale was completed at baseline, immediately after intervention, and at 1-month post-intervention. It is a 7-item self-report scale that asked participants to indicate how often they have experienced a series of anxiety symptoms in the past two weeks. Total scores range from 0 to 21, with higher scores indicating greater anxiety severity.
Time frame: Baseline, Immediately after intervention (18 weeks), 1 month post-intervention

Ran from Oct 2022 to primary completion in Oct 2024, 23 months.
Of 104 non-industry interventional studies with no phase under Developmental Disabilities, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 51. This study's 23 months is close to that.
Counting every sponsor, half of 105 studies reached it within 24 months; a quarter within 13 and three quarters within 51.
