Concurrent Treatments: Individuals who initiated any form of concurrent psychological or pharmacological treatment during the study period were excluded, as the interaction of multiple interventions could confound the results and lead to misleading findings regarding the comparative effectiveness of Acceptance and Commitment Therapy (ACT) versus Cognitive Behavioral Therapy (CBT). 2. Non-Adherence to Treatment Attendance: Participants who missed more than two therapy sessions for any reason were excluded from the data analysis to prevent the effects of inadequate intervention exposure from influencing the final outcomes. 3. Severe Psychiatric Disorders: Parents who themselves had severe psychiatric disorders (e.g., schizophrenia, bipolar disorder, major depressive disorder, or severe anxiety disorders) were excluded from the study. This was because the presence of such disorders could have a substantial influence on variables such as self-criticism and emotion regulation, potentially making the changes observed at post-test attributable not to the therapeutic intervention but rather to fluctuations in the underlying psychiatric condition.
