Abstract. Bollen and colleagues have advocated the use of formative scales despite the fact that formative scales lack an adequate underlying theory to guide development or validation such as that which underlies reflective scales. Three conceptual impediments impede the development of such theory: the redefinition of measurement restricted to the context of model fitting, the inscrutable notion of conceptual unity, and a systematic conflation of item scores with attributes. Setting aside these impediments opens the door to progress in developing the needed theory to support formative scale use. A broader perspective facilitates consideration of standard scale development concerns as applied to formative scales including scale development, item analysis, reliability, and item bias. While formative scales require a different pattern of emphasis, all five of the traditional sources of validity evidence apply to formative scales. Responsible use of formative scales requires greater attention to developing the requisite underlying theory.

Background: STIs, principally HIV/AIDS, are public health problems that are transmitted by sexual risk behaviours, which have been associated with the sexual sensation seeking (an specific personality factor). In South American context, there are no measurement instruments with psychometric evidence for their use and, in other contexts, only the Sexual sensation seeking scale (Kalichman et al., 1994) is available, which is outdated in content and validity evidence. The purpose of this work is development a scale, in accordance with contemporary psychometric standards, to assess sexual sensation seeking for South Americans young people and adults. Method: instrumental study, with time-space sampling (n=813) of undergraduate students from the two Chilean cities with the highest rates of HIV. Results: Final scale have 8 items to assess two dimensions: 1) sexual emotions seeking; and 2) tendency to sexual boredom. The identified structure provides adequate levels of reliability (ω> .8; α> .7), presents validity evidence, based on the internal structure of the test, using CFA and ESEM (CFI> .95, TLI> .95, RMSEA <. 06), and based on the convergence with other measures (sexual activity with multiple partners, inadequate or insufficient use of protective barriers and sexual activity under the influence of alcohol or drugs). Conclusions: The Multidimensional Scale of Sexual Sensation Seeking evidence adequate psychometric properties to evaluate the search for sexual sensations in equivalents samples.

Alternate assessments based on alternate achievement standards (AA-AAS) have historically lacked broad validity evidence and an overall evaluation of the extent to which evidence supports intended uses of results. An expanding body of validation literature, the funding of two AA-AAS consortia, and advances in computer-based assessment have supported improvements in AA-AAS validation. This paper describes the validation approach used with the Dynamic Learning Maps® alternate assessment system, including development of the theory of action, claims, and interpretive argument; examples of evidence collected; and evaluation of the evidence in light of the maturity of the assessment system. We focus especially on claims and sources of evidence unique to AA-AAS and especially the Dynamic Learning Maps system design. We synthesize the evidence to evaluate the degree to which it supports the intended uses of assessment results for the targeted population. Considerations are presented for subsequent data collection efforts.

This chapter addresses a wide range of concepts related to interpretation in qualitative research, examines the meaning and importance of interpretation in qualitative inquiry, and explores the ways methodology, data, and the self/researcher as instrument interact and impact interpretive processes. Additionally, the chapter presents a series of strategies for qualitative researchers engaged in the process of interpretation and closes by presenting a framework for qualitative researchers designed to inform their interpretations. The framework includes attention to the key qualitative research concepts transparency, reflexivity, analysis, validity, evidence, and literature. Four questions frame the chapter: What is interpretation, and why are interpretive strategies important in qualitative research? How do methodology, data, and the researcher/self impact interpretation in qualitative research? How do qualitative researchers engage in the process of interpretation? And, in what ways can a framework for interpretation strategies support qualitative researchers across multiple methodologies and paradigms?
