Causal and moral responsibility: Antecedents and consequences of group‐based guilt

In six studies (N = 1045) conducted in three European countries, we demonstrate distinctions between causal responsibility, group‐based guilt, and moral responsibility. We propose that causal responsibility is an antecedent of group‐based guilt linking the ingroup to previous transgressions against the victim group. In contrast, moral responsibility is a consequence of group‐based guilt and is conceptualized as a sociomoral norm to respond to the consequences of the ingroup's transgressions and the current needs of the victim group. As such, moral responsibility can be stimulated by group‐based guilt and directly predicts individual action intentions. Studies 1 and 2 focus on the conceptual distinctions among the three constructs. Study 3 tests the indirect effect of causal responsibility on moral responsibility via group‐based guilt. The remaining studies explore the mediating role of moral responsibility in associations between group‐based guilt and compensatory action tendencies, that is, financial compensation (study 4), approach and avoidance tendencies (study 5) and public apology (study 6). Together these studies show that causal and moral responsibility are psychologically distinct concepts from group‐based guilt and that moral responsibility plays an important role in shaping the effects of group‐based guilt on behavioral intentions.

Patient utilization of cognitive-behavioral therapy for OCD

The current study examined utilization of cognitive-behavioral therapy (CBT) by individuals receiving treatment for obsessive-compulsive disorder (OCD). Participants were 202 adults with primary DSM-IV OCD who enrolled in a longitudinal, observational study of the course of OCD and completed 2 years of annual follow-up interviews using the Longitudinal Interval Follow-Up Evaluation. One hundred twenty participants reported that a mental health professional recommended CBT for their OCD symptoms at some point during the 2-year follow-up period. One quarter (n = 31) of these participants did not initiate CBT despite receiving a treatment recommendation. Thirty-one percent of the 89 participants who entered CBT endorsed dropping out of CBT prematurely and less than one third received an adequate “dose” of CBT sessions. Self-reported CBT drop-out rates were significantly greater than attrition rates reported in clinical trials using intensive schedules of exposure and ritual prevention (EX/RP). Perceived environmental barriers and fears regarding treatment participation were the most frequently endorsed reasons for not participating or dropping out of CBT. Despite its efficacy for OCD, many individuals with clinically significant symptoms fail to initiate CBT when recommended by a mental health professional, receive treatments that are less intensive than those used in clinical trials, or drop out of treatment prematurely. Financial costs of CBT, difficulty attending sessions, and fears regarding treatment are significant barriers to initiating and completing therapy.     

Simultaneous contrast: evidence from licking microstructure and cross-solution comparisons

The microstructure of rats' licking responses was analyzed to investigate both "classic" simultaneous contrast (e.g., Flaherty & Largen, 1975) and a novel discrete-trial contrast procedure where access to an 8% test solution of sucrose was preceded by a sample of either 2%, 8%, or 32% sucrose (Experiments 1 and 2, respectively). Consumption of a given concentration of sucrose was higher when consumed alongside a low rather than high concentration comparison solution (positive contrast) and consumption of a given concentration of sucrose was lower when consumed alongside a high rather than a low concentration comparison solution (negative contrast). Furthermore, positive contrast increased the size of lick clusters while negative contrast decreased the size of lick clusters. Lick cluster size has a positive monotonic relationship with the concentration of palatable solutions and so positive and negative contrasts produced changes in lick cluster size that were analogous to raising or lowering the concentration of the test solution respectively. Experiment 3 utilized the discrete-trial procedure and compared contrast between two solutions of the same type (sucrose-sucrose or maltodextrin-maltodextrin) or contrast across solutions (sucrose-maltodextrin or maltodextrin-sucrose). Contrast effects on consumption were present, but reduced in size, in the cross-solution conditions. Moreover, lick cluster sizes were not affected at all by cross-solution contrasts as they were by same-solution contrasts. These results are consistent with the idea that simultaneous contrast effects depend, at least partially, on sensory mechanisms.     

Sensory-motor deficits in children with developmental coordination disorder, attention deficit hyperactivity disorder and autistic disorder

Children who have been diagnosed with any one developmental disorder are very likely to meet diagnostic criteria for some other developmental disorder. Although comorbidity has long been acknowledged in childhood disorders, little is understood about the mechanisms that are responsible for the high level of comorbidity. In a series of studies, we have investigated the link between sensory-motor deficits and developmental disorders. Poor sensory-motor integration has long been implicated as a cause of motor problems in developmental disorders such as developmental coordination disorder (DCD), and our recent research has also investigated sensory-motor deficits in children with attention deficit hyperactivity disorder (ADHD) and autistic disorder. Based on a critical examination of relevant literature and some of our recent research findings, we argue that the importance of poor sensory-motor functioning in discriminating children with different disorders has been underestimated. Poor sensory-motor coordination appears to be linked to DCD, but not ADHD. Also, sensory-motor deficits in children with DCD and autistic disorder may provide insight into some of the social difficulties found in these groups of children. This research will increase our understanding of why children with one developmental disorder typically also have problems in other areas.     

The relationship between comorbid personality disorders and treatment received in patients with anxiety disorders

Few studies have addressed the relationship between the presence of a comorbid personality disorder and the amount of psychiatric treatment received by patients with an Axis I disorder. This issue has not been studied in patients with anxiety disorders. In a prospective, naturalistic, longitudinal study of anxiety disorders, 526 subjects were assessed with the Personality Disorder Examination, and types of treatment received in 1991 and 1996 were identified. In 1991, compared to subjects without a personality disorder, subjects with a personality disorder were as likely to receive medication and they received a greater number of medications. Subjects with borderline personality disorder were more likely to receive heterocyclic antidepressants and interventions characteristic of psychodynamic psychotherapy and cognitive therapy; they also reported receiving a greater number of medications and types of psychosocial treatment than other subjects. In 1996, subjects with borderline personality disorder were more likely to receive psychodynamic interventions. These findings suggest that in patients with an anxiety disorder, the presence of a comorbid personality disorder is associated with receiving a greater number of medications but not with a greater likelihood of receiving pharmacologic or psychosocial treatment. However, the presence of borderline personality disorder is associated with a greater likelihood of receiving, and receiving a greater number of, certain types of somatic and psychosocial treatments.     

Can We Use Hare’s Psychopathy Model within Forensic and Non-Forensic Populations? An Empirical Investigation

Although psychopathy construct (Self-Report Psychopathy Scale–Short Form [SRP–SF]) was assessed among various samples, prior research did not investigate whether the model proposed by Hare and colleagues can be used to capture psychopathy scores derived from forensic and nonforensic populations. The main objective of the current study was to test dimensionality, construct validity, and factorial invariance of the SRP–SF within prison (n = 730) and student (n = 2,506) samples. Our results indicate that the SRP–SF measure cannot be used in the same way within forensic and nonforensic samples, which may be due to the inclusion of criminal/antisocial traits as an integral part of psychopathy.
