Evaluating the validity of the Amharic Brief Pain Inventory among people with chronic primary musculoskeletal pain in Ethiopia

Table 5 Convergent validity between the Amharic versions of BPI and SF-36 subscales (N = 269)

SF-36	BPI Mean Pain Severity (95% CI)	BPI Mean Pain Interference (95% CI)
General health perception (GH) Average	−0.43^a (−0.03 to −0.52)	−0.50^a(−0.41 to −0.59)
Physical functioning (PF) Average	−0.41^a(−0.30 to −0.50)	−0.63^a(−0.55 to −0.70)
Role Functioning Physical (RLPH) Average	− 0.29^a(− 0.18 to − 0.40)	− 0.48^a(− 0.39 to − 0.56)
Role Functioning Emotional (RLEP) Average	−0.26^a(− 0.15 to − 0.37)	−0.43^a(− 0.33 to − 0.52)
Energy (EN) Average	−0.35^a(− 0.24 to − 0.45)	−0.45^a(− 0.35 to − 0.54)
Emotional Well-Being EM) Average	−0.33^a(− 0.22 to − 0.43)	−0.41^a(− 0.30 to − 0.50)
Social Functioning (SF) Average	−0.37^a(− 0.265 to − 0.471)	−0.52^a(− 0.43 to − 0.61)
Bodily Pain (BP) Average	−0.44^a(− 0.34 to − 0.53)	−0.58^a(− 0.50 to − 0.66)

Pearson correlation: ^aCorrelation is significant at the 0.01 level (1-tailed)
Sf = 36 scores: Higher scores indicate less impact on life, while lower scores indicate greater impact
BPI scores: Higher scores indicate a greater impact on life, while lower scores indicate a lesser impact
