Is playing exergames really exercising? A meta-analysis of energy expenditure in active video games

This article reports a meta-analysis of energy expenditure (EE) of playing active video games (AVGs). In particular, heart rate (HR), oxygen consumption (VO2), and EE were assessed and three moderators for the effects of AVGs--types of AVG, player age, and player weight status--were analyzed. The results show that playing AVGs significantly increased HR, VO2, and EE from resting. The effect sizes of playing AVGs on HR, VO2, and EE were similar to traditional physical activities. AVG type and player age were significant moderators for the effects of AVGs. The finding suggests that AVGs are effective technologies that may facilitate light- to moderate-intensity physical activity promotion.     

Stabilität posttraumatischer Intrusionen bei Polizeibeamten

Objectives

This prospective study examined the course of posttraumatic symptoms of police officers across a time span of 12 months (T1: directly, T2: 6 months and T3: 12 months) after confrontation with an event of potentially traumatic nature while on duty.

Method

A total of 50 police officers were diagnosed 6 months after the event (T2) using a structured interview (SCID-I and SCID-II). The global functioning was operationalized at T1 and T2 by the Global Assessment of Functioning Scale (GAF) and the degree of impairment by the Impairment Score (IS). Furthermore, the intensity of posttraumatic symptoms was assessed at T1 and T2 by the Impact of Event Scale - Revised (IES-R). After 12 months (T3) the intensity of posttraumatic symptoms of 40 police officers was assessed again by a mail enquiry.

Results

Of the police officers 14 (28%) received the diagnosis of post-traumatic stress disorder (PTSD) after 6 months. In the PTSD group a significant drop in the level of functioning and a significant increase in the degree of psychiatric impairment could be found. Concerning the stability of the intensity of posttraumatic intrusions (IES-R subscale intrusions) the PTSD group showed in comparison to the non-PTSD group a slower decrease of symptoms over the period of 12 months (ordinal interaction) and no such strong amelioration of the symptoms as for avoidance and hyperarousal could be found.

Conclusions

Although the police force are, due to pre-employment screening and the professional training, both mentally and physically healthy in comparison with the general population, the results point at the risk potential of exceptional events for police officers. Due to the fact that the intensity of posttraumatic intrusions remained on a relatively stable level it seems indispensable to render these police officers further professional support.     

First person plural: Roman Jakobson’s grammatical fictions

Roman Jakobson, who had left Russia in 1920 and in 1941 took refuge in the USA from the Nazis, was one of the main figures in post war linguistics and structuralism. Two aspects of his work are examined in this article. Firstly, Jakobson purifies his linguistic theory of pragmatic references. Secondly, he develops his own diplomatic mission of mediating between East and West. In this article, I argue that these two aspects did not develop independently from one another. Instead I claim that his theory is designed to slip through the Iron Curtain, while at the same time providing the means to analyse ways of acting politically by using language. This argument is unfolded in two steps, each consisting of two parts. First, I compare the theory of pronominal expressions as developed by Emil Benveniste to Jakobson’s theory of shifters. While Benveniste focuses on the relation of language and its subject using language, Jakobson introduces a model of communication to allow maximal formalisation of language. According to this even the category of person can be freed from its reference to a subject which would be understood as having a place in space and time. Then, Jakobson’s theory of shifters is studied in relation to his analyses of poetry. For this, two examples are chosen: Jakobson’s text on two poems by Russian poet Alexandr Blok, and his text on a poem by Bertold Brecht. In both texts, the theory of shifters—and the alleged purification from pragmatic aspects of language use ensuing from this theory—is challenged by the simple fact that they focus on the pronoun of the first person plural. According to Jakobson, the category of number does not belong to the shifters. Rather, number quantifies participants of the related event. The pronoun ‘we’ is at the same time a shifter and a non-shifter, as it refers to the speech event and the related event. Thus the pronoun ‘we’ opens up the possibility to include or exclude the participants of a communicative situation, and thereby enables the speaker to act socially or even politically by using language. The article concludes by coming back to the historical situation in which Jakobson developed his analyses of poetry. Analysing poetry seems to have been a passe-partout for him, a seemingly harmless subject that allowed him to get a foot in the door of remote and secluded lecture halls.     

Developing an indicator of family function and a practicable outcome measure for systemic family and couple therapy: the SCORE

There is a need for a measure of outcome in systemic family and couples therapy (SFCT) that reflects current theory and practice. To meet the needs of SFCT practice the measure needs to use self‐report by family members, take a short time to complete and be easy to understand. The development of such a measure, called the SCORE, is reported in this article. Substantial piloting, consultation and review in terms of clinical judgement led to the construction of the SCORE 40 which has forty items about how the family functions, rated by family members over 11 years of age on a Likert scale, in addition to independent ratings of the family and its difficulties. The SCORE 40 is shown to be a viable instrument but is too substantial for everyday clinical use. In a research project to reduce and refine the measure and determine its psychometric properties the SCORE 40 was administered to 510 members of 228 families at the start of their first appointment for family therapy at clinics throughout the UK. The scale has good psychometric properties and could operate with either three or four dimensions. The analyses of these data, combined with data from a convenience sample of 126 non‐clinical families, allowed a reduction to fifteen items while retaining most of the information provided by the SCORE 40. This version is offered with three dimensions of: (1) Strengths and adaptability; (2) Overwhelmed by difficulties; and (3) Disrupted communication. It is hoped that the ready availability of the SCORE 15 will encourage routine evaluation of outcomes in clinics as well as the SCORE being used flexibly for both therapy and research.     

The Future of Psychotherapy: Visions and Recommendations

Using a roundtable discussion format, the editor and new members of the editorial board for the Journal of Contemporary Psychotherapy exchange ideas about how they envision the future of psychotherapy, anticipate likely positive and negative outcomes, identify key issues to be confronted today in order to maximize future success, and clarify the role of the individual psychotherapist in protecting psychotherapy as a viable field of study and practice. The discussion closes with recommendations for the next generation of psychotherapists and general conclusions about the future of psychotherapy.     

The symbolic and concrete: Psychotic adolescents in psychoanalytic psychotherapy

Unique disturbances in symbolisation are characteristic of the pathology of schizophrenia. Drawing on the case vignette of a psychotic adolescent, the author discusses theoretical problems in the symbolisation process in general and then in psychosis, in particular the relation between 'concretism' as a thought disorder and other psychotic defences. The ability to symbolise on the one hand and to maintain sufficiently stable ego boundaries on the other hand are examined in their relation. The author's clinical experience supports her hypothesis that there is a close relationship between the impairment of the symbolisation process in the adolescent or adult psychotic patient and his/her inability to engage in symbolic play as a child. Special attention is paid to the role of early trauma and consequent pathology of object relations for disturbances of symbolic play in childhood. Regression to concrete thinking is understood as the chance of the psychotic patient to give some meaning to reality in an unreal, delusional world and as his/her last chance to communicate at all. Conclusions are drawn for psychoanalytic techniques in the treatment of patients who are deeply regressed in this respect. Special attention is given to the particular circumstances and challenges of adolescence and to providing psychoanalytic psychotherapy to adolescent psychotic patients.     

Toward A Typology Of Abusive Women: Differences Between Partner-Only And Generally Violent Women In The Use Of Violence

Based on previous typologies of domestically violent men ( Holtzworth-Munroe & Stuart, 1994 ), women who were referred to a treatment agency for abusive behavior  ( N = 52)  were categorized into two groups based on the breadth of their use of violence: Partner-Only (PO) and Generally Violent (GV). PO women were hypothesized to use reactive violence, for example, out of fear or in self-defense, whereas GV women were hypothesized to use instrumental violence, that is, in order to exert control. Self-defense was assessed in three different ways and convergent validity was demonstrated for these three new measures. GV women reported using instrumental violence more than PO women, in a variety of situations. GV women tended to report more traumatic symptoms than PO women, although they did not experience significantly more abuse. GV women were more likely to witness their mothers' physical aggression. Thus, we theorize that GV women have been socialized to believe that it is acceptable for women to use violence to resolve conflict. Trauma history and violent socialization should be addressed clinically.     

Men's likelihood of sexual aggression: the influence of alcohol,sexual arousal,and violent pornography

Previous research findings have indicated that both alcohol intoxication and violent pornography exposure may contribute to increased sexual aggression by men. This study used an experimental paradigm to examine the effects of a moderate alcohol dose, alcohol‐related beliefs, and victim response on men's self‐reported likelihood of committing sexual aggression. A community sample of male social drinkers (N=84) participated in an experiment in which they read an eroticized rape depiction after completing an alcohol administration protocol. The stimulus story varied whether the victim, who initially expressed unwillingness to engage in sexual activity, expressed pleasure or distress in response to the man physically forcing her to perform several explicit sex acts. A path analytic model illustrated that participants' self‐reported likelihood of behaving like the sexual aggressor in the story was directly related to their own sexual arousal. Heightened sexual arousal was reported by participants who had consumed alcohol, those who read the victim‐pleasure story, and those who believed that drinking women are sexually vulnerable. Results suggest that sexual arousal to violent pornography, as influenced by acute alcohol intoxication and other factors, may be an important component of men's perceptions of their own sexual aggression likelihood.
