The Use of a Deviation Line in Contingency Contracting for Weight Control.
Jones, Duane L.; Jensen, Carl B.
Contingency contracting has been demonstrated to be an effective procedure for achieving weight loss. A problem with this type of contract is that the S may have to permanently forfeit an item for a failure to lose weight when in fact his/her eating behavior has been appropriate. The following procedure was developed to overcome this problem. A projected weight loss line (PWL) and a deviation line (DL) were drawn on a graph. At any deadline when the S's weight was above the PWL, the subject was temporarily denied access to an item until the next weigh-in when the S's weight fell on or below the PWL. On any deadline when the S's weight fell above the DL, the S permanently forfeited one reinforcer for every pound above the DL. Two female Ss participated in the program. A reversal design demonstrated the effectiveness of these procedures. (Author/CKJ)
