This paper assesses the psychometric properties of the Student Motivation Scale, an instrument measuring school students' motivation. Motivation is assessed through nine measures, separated into what are referred to as boosters and guzzlers. Boosters are constructs that reflect adaptive motivation and guzzlers are constructs that reflect less adaptive motivation. Boosters are subsumed by thoughts (self-belief, learning focus, value of schooling) and behaviours (persistence and planning and monitoring). Guzzlers are subsumed by thoughts or feelings (low control and anxiety) and behaviours (avoidance and self-sabotage). Data show that the Student Motivation Scale has a clear factor structure reflecting the hypothesised five boosters and four guzzlers, is reliable, and correlated with achievement. Gender and year level differences also emerge: girls are significantly more learning focused and engage in more planning and monitoring than boys; girls are significantly more anxious than boys; Year 9 students are significantly lower than Year 10 and Year 11 students in learning focus, significantly higher than Year 11 students in avoidance, and significantly higher than Year 10 and Year 11 students in self-sabotage. Strategies for intervention are discussed in the context of these findings and the issue of academic resilience is introduced as an additional aspect of motivation that the Student Motivation Scale is able to assess.

Adequate Internal Consistency

AbstractThis article presents the development of an instrument measuring relationship satisfaction, based on the theory that separates ‘relationship quality’ from ‘satisfaction’ concerning the semantic meaning of the concepts, and to evaluate psychometric properties of the new measure. Two studies were conducted in order to investigate the psychometric properties of the new scale, with 372 and 1,185 participants taking part in Study 1 and Study 2 respectively. Results revealed that the new scale has two-factor structure, adequate internal consistency reliability, and convergent, discriminant and known-groups validity.

Before evaluating convergent, discriminant, and known-groups validity, it is suggested to design an instrument that reflects hypothetical relationships or differences with other comparator instruments or groups. For criterion validity, a gold-standard instrument measuring the same construct should be carefully selected.

Type Ii Errors

Background: Our examination in multiple sclerosis (MS) of the ABILHAND, a patient-reported outcome (PRO) instrument measuring manual ability, identified limited measurement range and precision. These deficiencies could lead to type II errors in clinical trials. Objectives: This paper aims to determine if ABILHAND’s measurement performance in MS can be improved by adding relevant items from the Disabilities of the Arm, Shoulder and Hand scale (DASH). Methods: The 23-item ABILHAND and 30-item DASH were administered to 461 people with MS. Data from the ABILHAND were combined with 16 DASH items to create a 39-item scale (AD-39). Using Rasch Measurement Theory methods, we compared the psychometric properties of AD-39 with ABILHAND. Results: Data were analysed from 300 people. AD-39 performed robustly as a measure and had greater measurement range, lower floor and ceiling effects, and higher reliability (person separation index 0.97) than ABILHAND. Surprisingly, AD-39 appeared no better than ABILHAND at detecting group differences in self-reported hand function. Conclusion: Despite improving some psychometric properties, adding 16 DASH items to the ABILHAND did not improve its measurement performance to the degree expected. Our explanations for this anomaly emphasise the importance of evidence-based, conceptually driven scale modifications guided by hypothesis testing psychometric methods.

Online studies are increasingly utilized in applied research. However, lack of external diagnostic verification in many of these investigations is seen as a threat to the reliability of the data. The present study examined the robustness of internet studies on psychosis against simulation. We compared the psychometric properties of the Community Assessment of Psychic Experiences scale (CAPE), a self-report instrument measuring psychotic symptoms, across three independent samples: (1) participants with a confirmed diagnosis of schizophrenia, (2) participants with self-reported schizophrenia who were recruited over the internet, and (3) clinical experts on schizophrenia as well as students who were asked to simulate a person with schizophrenia when completing the CAPE. The CAPE was complemented by a newly developed 4-item psychosis lie scale. Results demonstrate that experts asked to simulate schizophrenia symptoms could be distinguished from real patients: simulators overreported positive symptoms and showed elevated scores on the psychosis lie scale. The present study suggests that simulated answers in online studies on psychosis can be distinguished from authentic responses. Researchers conducting clinical online studies are advised to adopt a number of methodological precautions and to compare the psychometric properties of online studies to established clinical indices to assert the validity of their results.

Purpose This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method Participants in the ENNI database included 300 children with typical language (TL) and 77 children with language impairment (LI) between the ages of 4;0 (years;months) and 9;11. Narrative samples were collected using a story generation task, in which children were asked to tell stories based on six picture sequences. CD was computed from the narrative samples. The split-half reliability, concurrent criterion validity, and diagnostic accuracy were evaluated for CD by age. Results CD scores increased significantly between ages 4 and 9 years in children with TL and those with LI. Children with TL produced higher CD scores than those with LI at each age level. In addition, the correlation coefficients for the split-half reliability and concurrent criterion validity of CD scores were all significant at each age level, with the magnitude ranging from small to large. The diagnostic accuracy of CD scores, as revealed by sensitivity, specificity, and likelihood ratios, was poor. Conclusions The finding on diagnostic accuracy did not support the use of CD for identifying children with LI between ages 4 and 9 years. However, given the attested reliability and validity for CD, reference data of CD from the ENNI database can be used for evaluating children's difficulties with complex syntax and monitoring their change over time.
