Traumatic Brain Injury: (Brown et al, 2004; community dwelling individuals with TBI; n=454)
- Poor correlation of the PO and the PS Total scores (0.23 for the group with mild TBI, 0.21 for the group with moderate-severe TBI)
- Poor correlations were also found with respect to PO total score correlations with PS subscale scores, and the PS total score with PO subscale scores
- Stronger correlations in both groups (mild TBI and moderate to severe TBI) , was found of “subjective” measures (ie, BISQ, BDI II, Flanagan QOLS, Life 3) with the PS than with the PO total scores
- Current age, injury severity, and years post-TBI onset were not related to PO or to PS total scores

Traumatic Brain Injury: (Cantor et al, 2008; n=223 community-dwelling individuals with mild to severe TBI and 85 non-injured controls)
- None of the index scores, including the POPS total scores, were significantly correlated with Global Fatigue Index (GFI) for either group
- 5 of 26 individual POPS objective participation items were correlated with GFI scores (cleaning house, paying bills, visiting friends, engaging in sex, and speaking to neighbors), with poor correlation coefficients from –0.141 (P = .041) to –0.163 (P = .020)
- Partial correlations controlling for gender in the TBI group and gender and income in the control group:
- 13 individual items on the GFI pertaining to the impact of fatigue on participation with responses to POPS items (shopping for groceries, cleaning house, cooking, working, attending school, socializing with friends and relatives in per-son and by phone, engaging in sex, participating in recreational activities such as movies, dining out, shopping, and sporting events)
- TBI group: significant negative correlation between frequency of sexual activity and the extent to which participants thought fatigue interfered with their sex lives (r=–0.169, P=.036). However, none of the other correlations were significant for either group.
Traumatic Brain Injury: (Curtin et al, 2010; n=131 individuals with TBI from rural brain injury facilities; mean age=40.83 (11.77); male=69.7% and female=32.1%; time post-TBI=8.35 (6.29) years)
*Changes to the POPS items based on feedback: the original item about travelling in a car was split into two questions (one on driving a car and one on being a passenger in a car), increasing the number of items to 27; and a question about frequency of sexual intercourse changed to ask instead about intimacy with another person.
- The relationships between the PO scores were generally fairly low
- Higher correlations for PS observed
- Positive relationship between the objective and subjective rating for each area other than for transport, suggesting that the higher the level of activity, the greater the satisfaction
- The relationships tend to be relatively small and there is no relationship between the objective total scores and the subjective total scores
- No relationship was found between the POPS scores and gender and there was no relationship with time since TBI
