Key result

Type D personality occurs in 50% of chronic low back pain patients, correlating with greater disability.

  • P=0.011
  • n=68

Why the study?

The study aimed to compare Type D personality traits and self-esteem between individuals with chronic NSLBP and healthy controls, and explore their associations with functional status, psychological symptoms, and quality of life.

Is Type D personality associated with worse disability, psychological symptoms, and quality of life in patients with chronic nonspecific low back pain?

Population

34 patients with chronic NSLBP and 34 healthy controls

Comparison

Patients with chronic NSLBP vs healthy controls

Design

Cross-sectional investigation

Implication

Does not support routine Type D screening in chronic NSLBP; hypothesis-generating for targeted psychological interventions.

Key Points

  • This research aims to investigate the links between Type D personality traits, self-esteem, disability, and quality of life in individuals with chronic nonspecific low back pain.
  • Cross-sectional design comparing 34 patients with chronic NSLBP and 34 healthy controls
  • Assessment tools included VAS for pain intensity, ODI for functional impairment, DS14 for Type D personality, RSES for self-esteem, HADS for anxiety and depression, and SF-12 for quality of life
  • Statistical analyses compared proportions, means, and correlations across groups.
  • Type D personality was more prevalent in the NSLBP group (50%) than in controls (20.6%, p=0.011)
  • Patients with NSLBP exhibited higher NA scores (p<0.001) and lower SF-12 Physical Component Summary scores (p<0.001) than controls
  • Type D traits correlated with higher VAS (p=0.004) and ODI scores (p=0.007) and lower SF-12 Mental Component Summary scores (p=0.003).

Study Design

Type

Cross-Sectional (n=68)

Structured PICO

Is Type D personality associated with worse disability, psychological symptoms, and quality of life in patients with chronic nonspecific low back pain?

P
Population
68 individuals, comprising 34 patients with chronic nonspecific low back pain (NSLBP) and 34 healthy controls with similar age and sex distribution.
I
Intervention
Type D personality (observational exposure)
C
Comparator
Healthy controls and patients without Type D personality
O
Outcome
Prevalence of Type D personality, pain intensity (VAS), functional impairment (ODI), psychological symptoms (HADS), and quality of life (SF-12)patient reported

Main Result

Absolute Event Rate: 50% vs 20.6%

p-value: p=0.011

Type D personality is more prevalent in patients with chronic nonspecific low back pain and is associated with greater pain intensity, disability, and poorer mental quality of life.

Limitations

  • Cross-sectional framework
  • Potential construct redundancy between negative affectivity and emotional distress
  • Cannot establish definitive causality
  • cross-sectional framework
  • potential construct redundancy between NA and emotional distress

Cite This Study

Bakırcı et al. (2026) conducted a cross-sectional in Chronic nonspecific low back pain (n=68). Chronic nonspecific low back pain vs. Healthy controls was evaluated on Type D personality prevalence (p=0.011). Chronic nonspecific low back pain was associated with a higher prevalence of Type D personality than healthy controls (50% vs. 20.6%, p=0.011), which correlated with greater pain and disability.
