Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure of this study is the severity of the depressive symptoms measured with the BDI-II-NL. The score-range of this 21-item questionnaire is 0 to 63. Higher scores reflect more severe depressive symptoms. Several studies have shown that the BDI-II is a strong screening measure for depression (Beck, Steer, & Brown, 1996; van der Does, 2002; Whisman, Perez, & Ramel, 2000). It is a widely used instrument measuring the severity of depression. In 1998 the BDI had already been used in over 2000 studies (Richter, Werner, Heerlein, Kraus, & Sauer, 1998). | — |
