ObjectiveThe present study attempted to explore the psychological experiences of experiential avoidance, thought suppression, meta‐cognition, self‐compassion and body‐checking during two stages of maternity (pregnancy and postpartum) among women embracing maternity for the first time.MethodsThe study used a cross sectional correlational design and enrolled 306 women participants who were in their third trimester of pregnancy or of postpartum (pregnant = 154 [50.3%]; postpartum = 152 [49.7%]) with ages ranging between 20 and 35 years (M = 26.62; SD = 2.19). The data was collected using the Brief Experiential Avoidance Questionnaire (BEAQ); Thought Control Questionnaire (TCQ); Metacognitions Questionnaire (MCQ); Self‐Compassion Scale (SCS), and Body‐checking Questionnaire (BCQ). Data was subjected to statistical analysis using SPSS version 21.ResultsA significant positive association was observed between experiential avoidance, thought suppression, meta‐cognition, and body‐checking while self‐compassion showed reverse association with these variables. The body‐checking outcome was significantly negatively predicted by self‐compassionate attitude and positively by thought suppression in both groups (i.e., pregnant and postpartum). The experiential avoidance positively predicted body‐checking among women in post‐partum group only. Moreover, a mediating association of experiential avoidance and a moderating effect of self‐compassion (self‐kindness and common humanity) and meta‐cognition (positive beliefs about worry and need to control thought) were also observed to moderate between thought suppression and body‐checking outcomes.ConclusionThe study concluded that experiential avoidance and thought suppression contribute in developing body‐checking behaviors among women who are pregnant or at postpartum stage of maternity. In addition, self‐compassion and meta‐cognition moderate this association with self‐compassion playing potential buffer.
