The concept of placebo

This paper attempts to define the concept of placebo as it is used in the clinical context The author claims that X is a placebo if and only if X has such a property d_p, that whenever in a therapeutic situation T a stimulus S appears, then in attending conditions A, it will cause a beneficial reaction R in the patient. Formally, the same structure may be used to define any pharmacologically active drug. The main difference between the drug and a placebo is in the range of possible substitutions for X and the property d. For the active drug there is only one possible substitution for X and property d and it can be scientifically explained why, and how the drug works. In the case of a placebo a set of possible substitutions for X and d is open, and so far it is impossible to offer any scientifically valid explanation of the action mechanism of placebo.     

Comparing Holographic Reprocessing and Prolonged Exposure for Women Veterans with Sexual Trauma: A Pilot Randomized Trial

This pilot study compares an emerging evidence-based treatment, holographic reprocessing (HR) to prolonged exposure (PE) versus a person-centered (PC) control group to treat symptoms of distress in female Veterans with sexual trauma. In contrast to PE, HR does not include exposure to a target event of trauma. Instead, HR focuses on healing the internal working model or type of attachment style that may form as a result of interpersonal trauma or maltreatment. The model reveals how people perceive themselves and others. These perceptions set in motion emotional, cognitive, and behavioral tendencies wherein people unconsciously replicate similar types of relationships that reinforce their worldview. Fifty-one female Veterans with sexual trauma were randomly assigned to one of three treatments and completed pre- and post-treatment measures of psychiatric symptoms (anxiety, depression, and PTSD) and post-traumatic cognitions. ANOVAs found significant decreases on all variables. Post-hoc comparisons revealed that HR and PE treatments demonstrated significantly greater decreases in symptoms compared to the PC control group. Chi square analyses revealed that HR produced a significantly lower dropout rate 1 (6 %) compared to PE 7 (41 %) and PC 6 (35 %). These initial results are promising and further investigation of HR is warranted.

Sensation-seeking and preference for emotional visual stimuli

The Zuckerman Sensation-seeking Scale (SSS) was administered to 190 men and 197 women, who were also asked to choose 5 pictures out of a group of 21. Seven of these pictures had been rated as emotionally positive, 7 as emotionally neutral and 7 as emotionally negative. Choices of the high and low sensation-seeking groups were compared, and it was found that the high sensation-seekers had a stronger preference for the hegative stimuli than the lows, and the low sensation-seekers had a stronger preference for the positive stimuli than the highs. The results are discussed in terms of optimum level of arousal.     

Newborn Screening for Cystic Fibrosis: Parents’ Preferences Regarding Counseling At the Time of Infants’ Sweat Test

Newborn screening (NBS) protocols for cystic fibrosis (CF) are the first regional population-based programs to incorporate DNA analysis into their procedures. Research about these programs can inform policy and practice regarding how best to counsel families with abnormal NBS results. The grounded theory method guided interviews with 33 families whose infants had abnormal CF NBS results. A dimensional analysis of these interviews provided a theoretical framework describing parents’ preferences regarding counseling during their infant's sweat test appointment. This framework describes the contexts and characteristics of the two main dimensions of parents’ preferences: factual information and emotional support. Factual information included learning about the probability of a CF diagnosis, CF disease facts, sweat test procedure, and CF genetics. Social support consisted of offering parents a choice about the timing and amount of CF information, showing empathy for their distress, instilling hope, personalizing counseling, and providing hospitality. This framework also explains the consequences of counseling that matched versus mismatched parental preferences in these domains. Counseling that matched parents preferences reduced parents’ distress while mismatched counseling tended to increase parents’ worry about their infant.     

Neuroticism and marital satisfaction

Thirty happily married and thirty unhappily married couples were examined by means of the MPI questionnaire to test the hypothesis that emotional instability impaired satisfaction in marriage. Unhappily married partners were very significantly higher on neuroticism than happily married partners, but there were no differences in extraversion/introversion. The data suggest that the high neuroticism of the unhappily married partners antedates their marriage.     

Psychoticism and marital satisfaction

The author has tested the hypothesis that psychoticism, as described in Eysenck's theory of personality, is related to marriage outcome. Thirty happy and 30 unhappy couples answered the Eysencks' EPQ questionnaire. The unhappy husbands and unhappy wives scored significantly higher on the P scale than their happy counterparts respectively. The results suggest that psychoticism (like neuroticism) may impair the marriage satisfaction. In addition, happily married spouses show greater similarity with respect to personality than do unhappily married spouses. Thus the results support the likeness and go counter to the complementaries theories of marital satisfaction.
