Use these databases to obtain a comprehensive description/review of a test/measurement (i.e. reliability, validity, etc.), publisher information, administration, procedures, cost, audience, etc.
Finding an actual instrument can be difficult due to licensing or author restrictions. However, sometimes the instrument is included, and if not, article results may still reveal relevant content about the test and how it was used in the study. If available, the instrument will usually be located in the appendices. The list of references can also be checked for a possible instrument source location.
Appended should help you locate articles with the instrument included in the appendix of the article. There’s likely more info about the tests without the test included, so you might want to try the search without the term “appended” as well.

Measures of Personality and Social Psychological Constructs by
Measures of Personality and Social Psychological Constructs assists researchers and practitioners by identifying and reviewing the best scales/measures for a variety of constructs. Each chapter discusses test validity, reliability, and utility. Authors have focused on the most often used and cited scales/measures, with a particular emphasis on those published in recent years. Each scale is identified and described, the sample on which it was developed is summarized, and reliability and validity data are presented, followed by presentation of the scale, in full or in part, where such permission has been obtained. Measures fall into five broad groups. The emotional disposition section reviews measures of general affective tendencies, and/or cognitive dispositions closely linked to emotion. These measures include hope and optimism, anger and hostility, life satisfaction, self-esteem, confidence, and affect dimensions. Emotion regulation scales go beyond general dispositions to measure factors that may contribute to understanding and managing emotions. These measures include alexithymia, empathy, resiliency, coping, sensation seeking, and ability and trait emotional intelligence. The interpersonal styles section introduces some traditional social-psychological themes in the context of personality assessment. These measures include adult attachment, concerns with public image and social evaluation, and forgiveness. The vices and virtues section reflects adherence to moral standards as an individual characteristic shaped by sociocultural influences and personality. These measures include values and moral personality, religiosity, dark personalities (Machiavellianism,narcissism, and subclinical psychopathy), and perfectionism. The sociocultural interaction and conflict section addresses relationships between different groups and associated attitudes. These measures include cross-cultural values, personality and beliefs, intergroup contact, stereotyping and prejudice, attitudes towards sexual orientation, and personality across cultures.
Measuring Race and Ethnicity by
Racial and ethnic issues stand at the core of social, political, and economic concerns in an increasingly diverse America. Accordingly, how individuals from the various ethnic groups regard themselves--and others--is a salient focus of research studies across the disciplines. Measuring Race and Ethnicity gathers psychological measures of common phenomena such as racial identity, acculturation, and intra- and intergroup relations enabling researchers to compare concepts across groups and better evaluate differences and disparities.Researchers in psychology, social work, and public health examining cultural and race-related topics will find an immediately relevant source of valid and reliable scales in Measuring Race and Ethnicity.
