Propiedades Psicométricas del Inventario CABI Para la Determinación del TDAH. Psychometric Properties Of The Cabi Inventory In The Determination Of ADHD.

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequent mental health issues among children and adolescents

worldwide. Current literature shows that ADHD could affect both academic and work performances of those who present it. The aim of the present study was to analyze the psychometric properties of the Child and Adolescence Behavior Inventory (CABI) through an exploratory study, based on the report of 350 Chilean parents. Results indicated a three-dimensional model (sluggish cognitive tempo, inattention and hyperactivity) with adequate fit of the data (RMSEA=0.065; CFI= 0.954; TLI=0.941; PL=207) that explained 61.76% of the total variance with an Alpha of 0.961. Results show that the subscales analyzed have acceptable psychometric properties, an adequate internal consistency and that their indicators have a correct discriminatory power.

Therefore, according to these preliminary results, CABI can be considered a useful assessment tool for the diagnosis of ADHD. Implications for practice, policy and future research are discussed.

Development And Validation Of A Brief Scale To Assess Attachment In Adults: Psychometric Analysis In Latin America. Desarrollo y Validación de Una Escala Breve Para Valorar el Apego en Adultos: Análisis Psicométrico en América Latina

Assessment of the adult attachment in the Latin American context as a research line is not yet solved. This study has the aim to present the results of the development and validation of a scale to assess the adult attachment. The sample was composed of 1563 participants aged between 17 and 33 years from Chile and Ecuador. This scale was formed by 14 items, which allowed the assessment of secure attachment, avoidant attachment, and ambivalent attachment. Results are as following: (a) the scale presented an adequate internal consistency for secure attachment α=.73 and ω=.82, avoidant α=.58 and ω=.70, and ambivalent α=.69 and ω=.73; (b) adequate convergent validity with sense of coherence (r=.34 and .43, p=< .001); (c) the exploratory factor analysis kept up the items’ organization developed KMO=.77, x2=4133.91, p=<.001; and, (d) the confirmatory factor analysis presented a good fit with three items for each attachment type x2(24)=136.28, p=<.001, CFI=.95, RMSEA=.05(.04–.06), SRMR=.03. Findings of psychometric properties are discussed, highlighting the contribution of this scale in the Latin American context and its relationship with previous research.

Psychometric Properties Of ADHD Rating Scale In School Context. Propiedades Psicométricas de la Escala ADHD en el Contexto Escolar

Background: The ADHD Rating Scale IV (ADHD RS IV) is one of the most commonly used scales in attention deficit hyperactivity disorder (ADHD) assessment. Its psychometric properties have been studied in contexts including Europe and North America, however, in Latin America, there is shortage of empirical evidence about validity or reliability reported by teachers on a scholar context. The aim of the research was to analyze the psychometric properties of the ADHD RS IV based on the behavior of students reported by teachers. Material/methods: Three hundred and forty-five students voluntarily participated in this study (162 men and 183 women), aged between 5 and 15 years (Mage = 10.43, SD = 3.61). As instruments of measurement ADHD RS IV, Perception of Differences Test and Go / No-Go experiment were used. Cronbach’s alpha, Pearson correlation and confirmatory factor analysis were applied and analyzed. Results: In the results it was found that internal consistency coefficient of RS IV ADHD is between .93 and .97. There is a significant statistically correlation between the scale and the number of successes points in the Perception of Differences Test (r = -.55, p = < .001) and mistakes to stimuli no-go (r = .34, p = .002). The classic ADHD model of two factors had good indicators of goodness of fit x2(101) = 321.40, p < .001; CFI = .96; RMSEA = .08 (.07 to .09) and SRMR = .04. Conclusions: The article is finalized highlighting the ADHD RS IV has adequate psychometric properties in order to be applied in the school context.

Depression and Anxiety in Parkinson’s Disease, Metric Properties of the Beck´s Depression and Anxiety Inventories. A K2 Factorial Design.

Background: Study to investigate the concurrent validity of the Beck Depression Inventory and Beck Anxiety Inventory evaluation scales against the ICD-10.
Methods: A K2 factorial design for studying the metrics properties of the BDI and BAI in parkinsonian outpatients.
Results: 147 parkinsonian patients were included; 44 patients has anxiety and depression; only depression 19; only anxiety 31; finally 53 subjects don’t have depression or anxiety. The BDI AUC was [0.858]. The BAI AUC was of [0.907]. The cut score was of 14/15 for the BDI and 13/14 for the BAI. The factorial design resulted in the two factors (depression and anxiety) has the best functional correlation in the regression.
Conclusions: The results we present bear out this lack of dimensionality, since we found that the BDI AUC-measured discriminative ability for anxiety was [0.739]. With regard to the BAI, this is employed to discriminate the depressed, AUC values of [0.771].
