Multiple linear regression analysis investigating the influence of P3 behavior scores on somatization.
| Unstandardized B | 95% CI of B | Standardized β | p-value | ||
|---|---|---|---|---|---|
| Lower | upper | ||||
| Change in P3 positive behavior | −0.023 | −0.030 | −0.016 | −0.179 | <0.001 |
| Change in P3 destructive behavior | 0.040 | 0.023 | 0.058 | 0.122 | <0.001 |
| Sex (0 = Male; 1 = Female) | 0.418 | 0.270 | 0.567 | 0.148 | <0.001 |
| Marital status (0 = not married; 1 = married) | −0.085 | −0.177 | 0.008 | −0.047 | 0.073 |
| Providing COVID-19 care (0 = no; 1 = yes) | 0.200 | 0.106 | 0.293 | 0.115 | <0.001 |
| Education (0 = graduate level; 1 = undergraduate level) | 0.190 | 0.093 | 0.288 | 0.104 | <0.001 |
| Place of work (0 = non-residential care; 1 = residential care) | 0.093 | −0.007 | 0.193 | 0.051 | 0.070 |
n = 1,376; p-model <0.001; Variance Inflation Factor (VIF) <2; linear regression using backward elimination; adjusted R square: 0.109; excluded variables: profession: direct care and children: yes; dependent variable (somatisation score) was transformed using a natural log-transformation because of heteroscedasticity.
