An Experimental Test of the Effects of Parental Modeling on Panic-Relevant Escape and Avoidance Among Early Adolescents

Escape and avoidance behaviors play a prominent role in the maintenance and possibly development of panic disorder, yet the literature regarding the etiology of these emotion-regulation strategies is relatively underdeveloped. The current study experimentally tests hypotheses that parental modeling of escape during a well-established panic-relevant biological challenge increases panic-relevant escape and avoidance among offspring. Fifty physically and psychologically healthy early adolescents (28 females; M_age = 11.58; 86% Caucasian), stratified by gender, were randomly assigned to observe one of their parents (39 females; M_age = 40.04): either (a) model completing a 3-min voluntary hyperventilation exercise (no escape modeling group) or (b) model premature termination of a similar procedure (escape modeling group). Offspring in the escape modeling group demonstrated a stronger escape response by discontinuing their own challenge sooner than those in the no-escape modeling group (r = .70). No group differences emerged in terms of avoidance responding, as indexed by nearly identical responding in terms of delay time before initiating the challenge, respiration rate, and self-reported willingness to engage in a second proposed challenge. Results suggest that parental behaviors may play an important role in the development of some forms of panic-relevant responding. These preliminary findings may have important implications for future prevention programs targeting parents and at-risk youth.     

Establishing the feasibility of direct observation in the assessment of tics in children with chronic tic disorders

Behavior analysis has been at the forefront in establishing effective treatments for children and adults with chronic tic disorders. As is customary in behavior analysis, the efficacy of these treatments has been established using direct-observation assessment methods. Although behavior-analytic treatments have enjoyed acceptance and integration into mainstream health care practices for tic disorders (e.g., psychiatry and neurology), the use of direct observation as a primary assessment tool has been neglected in favor of less objective methods. Hesitation to use direct observation appears to stem largely from concerns about the generalizability of clinic observations to other settings (e.g., home) and a lack of consensus regarding the most appropriate and feasible techniques for conducting and scoring direct observation. The purpose of the current study was to evaluate and establish a reliable, valid, and feasible direct-observation protocol capable of being transported to research and clinical settings. A total of 43 children with tic disorders, collected from two outpatient specialty clinics, were assessed using direct (videotape samples) and indirect (Yale Global Tic Severity Scale; YGTSS) methods. Videotaped observation samples were collected across 3 consecutive weeks and two different settings (clinic and home), were scored using both exact frequency counts and partial-interval coding, and were compared to data from a common indirect measure of tic severity (the YGTSS). In addition, various lengths of videotaped segments were scored to determine the optimal observation length. Results show that (a) clinic-based observations correspond well to home-based observations, (b) brief direct-observation segments scored with time-sampling methods reliably quantified tics, and (c) indirect methods did not consistently correspond with the direct methods.     

A test of the relations between avoidance of panic-related situations and substance use, substance dependence, and depression among subclinical panickers

The hypotheses that among subclinical panickers, avoidance of panic-related situations would be associated with elevated substance use levels and increased likelihood of lifetime diagnoses of substance dependence and major depressive disorder (MDD) were tested. Findings confirmed that panic-related avoidance was associated with an elevated likelihood of lifetime diagnoses of nicotine and alcohol dependence as well as MDD, but not drug dependence. Panic avoidance was also related to relatively greater daily levels of cigarette and alcohol use.     

Self-Plagiarism in Academic Publishing: The Anatomy of a Misnomer

The paper discusses self-plagiarism and associated practices in scholarly publishing. It approaches at some length the conceptual issues raised by the notion of self-plagiarism. It distinguishes among and then examines the main families of arguments against self-plagiarism, as well as the question of possibly legitimate reasons to engage in this practice. It concludes that some of the animus frequently reserved for self-plagiarism may be the result of, among others, poor choice of a label, unwarranted generalizations as to its ill effects based on the specific experience (and goals) of particular disciplines, and widespread but not necessarily beneficial publishing practices.     

Foundations of Academic Freedom: Making New Sense of Some Aging Arguments

The article distinguishes between the various arguments traditionally offered as justifications for the principle of academic freedom. Four main arguments are identified, three consequentialist in nature (the argument from truth, the democratic argument, the argument from autonomy), and one nonconsequentialist (a variant of the autonomy argument). The article also concentrates on the specific form these arguments must take in order to establish academic freedom as a principle distinct from the more general principles of freedom of expression and intellectual freedom.     

Parenting-related childhood learning history and panic vulnerability: a test using a laboratory-based biological challenge procedure

A small but growing literature highlights specific parenting behaviors in increasing panic vulnerability among offspring. The current study examined the association between parenting-related instrumental and observational learning of sick-role behavior during childhood and reactivity to a panic-relevant biological challenge procedure that has evidenced predictive validity in terms of panic onset. Participants were 93 physically and psychologically healthy young adults (39 females; M_age = 23.41 years). As expected, results indicated that instrumental learning experiences involving (panic-relevant) arousal-reactive symptoms predicted increased post-challenge anxiety, arousal, and negative affective valence, even after accounting for variability associated with other theoretically relevant variables (e.g., anxiety sensitivity). Consistent with prior work, this learning history effect was specific to arousal-reactive, as opposed to arousal non-reactive, symptoms. Unexpectedly, observational learning was not related to challenge responding. Findings are discussed in terms of the potential role of parenting in etiologic models of panic development.     

Evaluating the role of contingency in differentially reinforced tic suppression

The current study evaluated the effects of tokens delivered on differential reinforcement of zero-rate behavior (DRO) schedules or noncontingently on tic suppression in 4 children with tics. Tic frequency was lower in 3 of 4 children when tokens were delivered contingent on the absence of tics than when tokens were delivered noncontingently.
