Phase changes were marked using the following criteria: (i) A-B occurred when all measurements for phase A had been obtained; (ii) B-A’ occurred when the intervention was complete; and (iii) phase A’ occurred with data collection three months after treatment ended
The pre-post comparison of the scores on the battery of scales showed a reduction tendency (see Table 2). Clinical scores on the IGD-20 Test and the CERV normalized from t1 to t6, and they remained stable three months after treatment ended (Table 2, t6 to t7). General symptoms as assessed by the YSR-Total and SCL-R-PSDI scales notably improved. Scores related to school (CBCL), social problems (YSR), and family conflict (FES) also improved following treatment (Table 2). To evaluate the effects of treatment on specific comorbid diagnoses, the scales of the MACI test were compared. Scores on these scales also decreased: C1: Depressive Affect (FF)pre = 108, FFpost = 55, Introversion (1)pre = 107, 1post = 70; C2: Peer Insecurity (E)pre = 111, Epost = 53, Anxious Feelings (EE)pre = 76, EEpost = 92; C3: Borderline Tendency (9)pre = 77, 9post = 46, Unruly (6A)pre = 71, 6Apost = 71; C4: FFpre = 66, FFpost = 29, 1pre= 104, 1post = 45. The only exceptions were the EE scale [Anxious Feelings] (for C2) and Scale 9 [Borderline tendency] (for C3), where no decreases occurred. To evaluate the therapeutic alliance and the patients’ degree of satisfaction, theWATOCI instrument was used (Corbella and Botella 2004) (Table 2). Positive scores highlight the four participants’ satisfaction with the treatment
