Psychometric properties of the Situational Inventory of Body-Image Dysphoria-Short form in a Spanish sample

The primary objective of this study was to translate and validate Situational Inventory of Body-Image Dysphoria-Short form (SIBID-S) in a Spanish population. The scale consists of 20 items to assess the frequency of dysphoric body-image emotions in certain situational contexts, using a five-point rating scale. The questionnaire was administered to 214 women between the ages of 14 and 29 years, from primary and secondary schools and a university. Principal components analysis indicated a one-factor structure for the entire sample and both younger (18) and older (or=18) participants. Internal consistency was high (0.94), and the test-retest reliability over 1 month ranged between 0.89 and 0.9…

Complexation and Electronic Communication between Corannulene-Based Buckybowls and a Curved Truxene-TTF Donor

Abstract: The association behavior of an electron-donating, bowl-shaped, truxene-based tetrathiafulvalene (truxTTF) with two corannulene-based fullerene fragments, C32H12 and C38H14, is investigated in several solvents. Formation of 1:1 complexes is followed by absorption titrations and complemented by density functional theory (DFT) calculations. The binding constants are in the range logKa=2.9–3.5. DFT calculations reveal that the most stable arrangement is the conformation in which the 1,3-dithiole ring of truxTTF is placed inside the concave cavity of the corannulene derivative. This arrangement is confirmed experimentally by NMR measurements, and implies that a combination of p–p and C…

A bis-exTTF macrocyclic receptor that associates C60 with micromolar affinity

An exTTF-based macrocyclic receptor that associates C(60) with a binding constant10(6) M(-1) in chlorobenzene at room temperature is described. This represents an improvement of 3 orders of magnitude with respect to the previous examples of exTTF-based receptors and one of the highest binding constants toward C(60) reported to date.

Telepsychology and Self-help: The Treatment of Fear of Public Speaking

Abstract This work presents a self-help, Internet-based telepsychology program for the treatment of public speaking fears. The system is comprised of 3 parts: The assessment protocol gives the patient information about his or her problem (i.e., amount of interference it creates in his or her life, severity, degree of fear and avoidance). The system also includes a structured treatment protocol, organized into separate blocks, reflecting the patient’s progress. This ensures that the patient does not skip any steps in the treatment (something quite common in traditional self-help manuals), which provides more control over the process. The treatment protocol is a cognitive-behavioral program t…

The acceptability of an Internet-based self-help treatment for fear of public speaking

ABSTRACT Several randomised controlled studies have shown the efficacy of Internet-based self-help treatments. These studies have centred their attention on axis I (efficacy) of the Guidelines for Empirically Validated Treatments, although there are a few studies that also take into account axis II (effectiveness). The aim of the present work was to test the acceptability of an Internet-based self-help program for fear of public speaking and to compare its acceptability with the same treatment administered by a therapist. Fifty-two participants suffering from social phobia were randomly selected to take part in one of these treatments. All participants reported being satisfied with the trea…

Electron transfer in a supramolecular associate of a fullerene fragment

Herein, we investigate the association of a fullerene fragment, hemifullerene C30H12, with an electron-donating bowl-shaped tetrathiafulvalene derivative (truxTTF). UV/Vis titrations and DFT calculations support formation of the supramolecular complex, for which an association constant of log Ka = 3.6±0.3 in CHCl3 at room temperature is calculated. Remarkably, electron transfer from truxTTF to C30H12 to form the fully charge-separated species takes place upon irradiation of the associate with light, constituting the first example in which a fullerene fragment mimics the electron-accepting behavior of fullerenes within a supramolecular complex.
