Acceptance and commitment therapy and behavioral activation for the treatment of depression: description and comparison

The field of clinical behavior analysis is growing rapidly and has the potential to affect and transform mainstream cognitive behavior therapy. To have such an impact, the field must provide a formulation of and intervention strategies for clinical depression, the "common cold" of outpatient populations. Two treatments for depression have emerged: acceptance and commitment therapy (ACT) and behavioral activation (BA). At times ACT and BA may suggest largely redundant intervention strategies. However, at other times the two treatments differ dramatically and may present opposing conceptualizations. This paper will compare and contrast these two important treatment approaches. Then, the relevant data will be presented and discussed. We will end with some thoughts on how and when ACT or BA should be employed clinically in the treatment of depression.     

Further Validation for the Santa Clara Strength of Religious Faith Questionnaire

This study further investigates the validity of the Santa Clara Strength of Religious Faith (SCSORF) questionnaire. Building and expanding upon prior research, the SCSORF, existing religiosity measures, mood, and personality adjustment scales were administered to three samples. Subjects included 290 university students and 232 recovering substance abusers. The results further validate the SCSORF as being a valid measure of strength of religious faith.     

The generality of selective observing

Four rats obtained food pellets by poking a key and 5-s presentations of the discriminative stimuli by pressing a lever. Every 1 or 2 min, the prevailing schedule of reinforcement for key poking alternated between rich (either variable-interval [VI] 30 s or VI 60 s) and lean (either VI 240 s, VI 480 s, or extinction) components. While the key was dark (mixed-schedule stimulus), no exteroceptive stimulus indicated the prevailing schedule. A lever press (i.e., an observing response), however, illuminated the key for 5 s with either a steady light (S+), signaling the rich reinforcement schedule, or a blinking light (S-), signaling the lean reinforcement schedule. One goal was to determine whether rats would engage in selective observing (i.e., a pattern of responding that maintains contact with S+ and decreases contact with S-). Such a pattern was found, in that a 5-s presentation of S+ was followed relatively quickly by another observing response (which likely produced another 5-s period of S+), whereas exposure to S- resulted in extended breaks from observing. Additional conditions demonstrated that the rate of observing remained high when lever presses were effective only when the rich reinforcement schedule was in effect (S+ only condition), but decreased to a low level when lever presses were effective only during the lean reinforcement component (S- only condition) or when lever presses had no effect (in removing the mixed stimulus or presenting the multiple-schedule stimuli). These findings are consistent with relativistic conceptualizations of conditioned reinforcement and extend the generality of selective observing to procedures in which the experimenter controls the duration of stimulus presentations, the schedule components both offer intermittent food reinforcement, and rats serve as subjects.     

Response rate viewed as engagement bouts: resistance to extinction

Rats obtained food pellets by nose poking a lighted key, the illumination of which alternated every 50 s during a session between blinking and steady, signaling either a relatively rich (60 per hour) or relatively lean (15 per hour) rate of reinforcement. During one training condition, all the reinforcers in the presence of the rich-reinforcement signal were response dependent (i.e., a variable-interval schedule); during another condition only 25% were response dependent (i.e., a variable-time schedule operated concurrently with a variable-interval schedule). An extinction session followed each training block. For both kinds of training schedule, and consistent with prior results, response rate was more resistant to extinction in the presence of the rich-reinforcement signal than in the presence of the lean-reinforcement signal. Analysis of interresponse-time distributions from baseline showed that differential resistance to extinction was not related to baseline differences in the rate of initiating response bouts or in the length of bouts. Also, bout-initiation rate (like response rate) was most resistant to extinction in the presence of the rich-reinforcement signal. These results support the proposal of behavioral momentum theory (e.g., Nevin & Grace, 2000) that resistance to extinction in the presence of a discriminative stimulus is determined more by the stimulus-reinforcer (Pavlovian) than by the stimulus-response-reinforcer (operant) contingency.     

Response rate viewed as engagement bouts: effects of relative reinforcement and schedule type.

The rate of a reinforced response is conceptualized as a composite of engagement bouts (visits) and responding during visits. Part I of this paper describes a method for estimating the rate of visit initiations and the average number of responses per visit from log survivor plots: the proportion) of interresponse times (IRTs) longer than some elapsed time (log scale) plotted as a function of elapsed time. In Part 2 the method is applied to IRT distributions from rats that obtained food pellets by nose poking a lighted key under various multiple schedules of reinforcement. As expected, total response rate increased as a function of (a) increasing the rate of reinforcement (i.e., variable-interval [VI] 4 min vs. VI 1 mi), (b) increasing the amount of the reinforcer (one food pellet vs. four pellets), (c) increasing the percentage of reinforcers that were contingent on nose poking (25% vs. 100%), and (d) requiring additional responses after the end of the VI schedule (i.e., adding a tandem variable-ratio [VR] 9 requirement). The first three of these variables (relative reinforcement) increased the visit-initiation rate. The tandem VR, in contrast, increased the number of responses per visit. Thus, variables that have similar effects on total response rate can be differentiated based on their effects on the componemts of response rate.

DSM-5: The intersectionality of spirituality,culture, and aging

Counselors practice with older adults whose religion and spirituality may be factors in assessment and treatment. The DSM-5 includes religion and spirituality as part of pathology or culture. This approach is supported in counselor education. Religion as a cultural derivative only reflects the human aspect of religion, not including a client’s perception of divine actions possibly beyond the human experience, i.e., a miracle. How does the clinician discern if a client’s experience reflects pathology or the possibility of some sort of miracle? This article includes strengths and limitations of a cultural definition of religious and spiritual experience with case applications.     

Combined Individual Cognitive Behavior Therapy and Parent Training for Childhood Depression: 2- to 3-Year Follow-Up

Fourteen children with significant depressive symptoms from an open clinical trial of Primary and Secondary Control Enhancement Training augmented with Caregiver–Child Relationship Enhancement Training, participated in a 2- to 3-year follow-up assessment. The results suggested that the significant decreases in depressive symptoms observed at posttreatment were maintained at 2- to 3-year follow-up. Mothers' reports of significant improvement of child psychosocial functioning were also maintained, providing social validation of the effects. Pretreatment child-rated mother-child relations predicted depressive symptoms at 2- to 3-year follow-up. These long-term data support the use of the combined intervention and suggest the need for further research on caregiver involvement in treatment.
