Basic psychological need satisfaction and frustration in major depressive disorder.

Area of Science:

• Psychology
• Clinical Psychology
• Well-being Research

Background:

• Basic Psychological Needs Theory (BPNT) links need satisfaction (autonomy, competence, relatedness) to well-being.
• Need frustration is linked to ill-being and depression, but research in clinical samples is limited.

Purpose of the Study:

• To investigate differences in basic psychological need satisfaction and frustration between adults with major depressive disorder (MDD) and non-depressed individuals.
• To examine need profiles in a clinical depression sample.

Main Methods:

• Survey data collected from adults with MDD (n=115) and a non-depressed comparison group (n=201).
• Need profiles analyzed using a linear mixed model (LMM).

Main Results:

• Depressed individuals reported significantly higher need frustration and lower need satisfaction across autonomy, competence, and relatedness compared to controls.
• The disparity between groups was more pronounced for frustration than satisfaction, particularly for relatedness and competence needs.
• LMM confirmed expected positive correlations between the three basic psychological needs.

Conclusions:

• This study provides the first evidence of substantial differences in need-based experiences between depressed and non-depressed adults.
• Findings support core tenets of Self-Determination Theory.
• Results suggest potential for tailoring depression therapies to address psychological needs.
