Unit 3 Search Documentation

The search dates and record counts are composite and illustrative of the method; the databases and the studies named are real.
Why Documentation Matters
A literature search that cannot be repeated cannot be checked. A committee reading the background chapter needs to know not only which studies were found but how, so that it can judge whether important studies were missed. This document records every database searched, the date, the exact string, the limits applied and the number of records returned, followed by the screening steps and their counts.
The Search Log
Business Source Complete, searched on a Tuesday in early February. The string combined three blocks of terms joined by AND, described below, limited to peer-reviewed journals published in English from 1980 onward. It returned 412 records.
ABI/INFORM, searched the same day with the same string and limits. It returned 338 records.
PsycINFO, searched two days later. Because PsycINFO indexes behavior analysis journals, the safety practice block was expanded to include behavioral terms, as described below. It returned 287 records.
NIOSHTIC-2, the federal occupational safety institute's own bibliographic database, searched the following week. Its interface does not support nested Boolean strings, so each block was searched separately and the results combined in a reference manager. It returned 109 records.
Together the four searches returned 1,146 records.
The Three Term Blocks
The supervisor block captured who delivers the practice: supervisor, foreman, first-line manager, team leader, shift lead and frontline leader, each with truncation where the database allowed.
The safety practice block captured what is delivered: safety communication, safety leadership, safety feedback, safety climate, safety coaching and, in PsycINFO and NIOSHTIC-2, behavior-based safety, observation and feedback, and performance feedback.
The setting block captured where: manufacturing, food processing, bakery, packaging, plant, production line and factory.
A record had to match at least one term from each block.
Inclusion and Exclusion Rules
Studies were included if they met five conditions: an empirical study, not a commentary or review; a manufacturing, processing or comparable production setting; an intervention or measured variable concerning supervisors' safety behavior or communication; at least one safety outcome, such as injuries, observed safe behavior, near misses or safety climate; and publication in English in a peer-reviewed outlet. Studies were excluded if they concerned only executives or organization-wide programs without a supervisory component, or only health care, construction or transport settings, unless a comparison with manufacturing was reported.
Screening and the Flow of Records
Of the 1,146 records, 343 were duplicates across databases, leaving 803. Titles and abstracts of those 803 were screened against the inclusion rules, and 739 were excluded, most often because they concerned organization-level safety programs or non-production settings. That left 64 articles read in full. Of those, 47 were excluded: 18 had no supervisory component, 14 were set outside production, 9 were reviews or commentaries and 6 reported no safety outcome. Seventeen studies were included.
Forward Citation Searching
Two studies were treated as anchors because of their direct relevance: Zohar (2002), which tested an intervention giving supervisors feedback on their safety-related exchanges, and Zohar (2000), which linked group-level safety climate to minor injuries. Their citing articles were searched in Google Scholar and screened by the same rules. This added no new studies that met all five conditions, though it surfaced several in construction, including Kines et al. (2010), which were noted for the framework but not included.
What the Search May Have Missed
The search relied on English-language databases and on the terms in the three blocks. Studies using other vocabularies, or published in practitioner outlets without peer review, would not have been found. Because behavior analysts describe their work in terms of observation and feedback rather than leadership, and because those terms were added only in two databases, the behavioral literature may be underrepresented. The search will be rerun with that vocabulary in all four databases before the background chapter is finalized.
A search is complete only for the vocabulary it used, and the behavioral vocabulary was used in only half the databases.
A Note for a Second Reader
A second reader repeating these searches with the same strings on the same dates should retrieve the same records, give or take indexing changes. The full strings, exactly as typed, appear in the appendix, together with the reference manager file used to remove duplicates.

Reading the GB 890 Unit 3 instructions
The third GB890 assignment asks you to document your literature search so that someone else could repeat it. Explain why documentation matters for the committee. Log every database alongside its search date, the string as typed, any filters set and how many hits came back, noting any database whose interface forced a different approach. Describe your term blocks and how they were combined. State your inclusion and exclusion rules as specific conditions. Report screening as a flow of records, giving the count left after each step and why each full text was set aside. Describe any citation searching from anchor studies. Then state honestly what the search may have missed, especially vocabularies you did not use everywhere, and what you will do about it. About seven pages, with the full strings in an appendix and a flow diagram of records, is common for this unit.
How the GB 890 Unit 3 example is put together
The documentation opens by explaining why a search that cannot be repeated cannot be checked. A log records each database, with 412, 338, 287 and 109 records and the NIOSHTIC-2 workaround for nested strings. Three term blocks are listed, with behavioral terms added only in two databases. Five inclusion conditions and the exclusion rules follow. The flow of records runs from 1,146 to 803, 64 and 17, with the 47 full-text exclusions tallied by reason. Forward citation searching from Zohar's two studies adds construction studies such as Kines and colleagues for the framework only. The section on what may have been missed, with the highlighted sentence on vocabulary, commits to rerunning the behavioral terms in all four databases.
Reading the GB890 Unit 3 grading rubric
The GB890 search documentation earns points for reproducibility and candor. Instructors give credit for exact strings with dates and yields for every database, since summaries cannot be repeated. Explaining interface limitations, such as a database without nested searching, shows care. Term blocks should be described so a reader can see why a study would or would not be retrieved. Inclusion rules must be specific conditions, not general relevance. A flow of records with counts and exclusion reasons at each stage is weighted heavily. Citation searching from named anchors shows thoroughness. Stating what the search may have missed, and planning to address it, is often a separate rubric point. Accurate citation of anchor studies is expected throughout the document.
GB890 Unit 3 help: mistakes that cost points
Many GB890 search write-ups name databases and a few keywords but leave out what was typed, when and how much came back, so nobody can rerun them. Others report only the final number of studies. Inclusion rules are often vague, such as studies relevant to safety leadership. Exclusion reasons at the full-text stage are rarely tallied. Students frequently miss literature that uses a different vocabulary for the same practice. Limitations sections tend to say only that some studies may have been missed. Record every string with its date and yield, describe the blocks, state specific inclusion rules, report the flow with counts and reasons, document citation searching, name the vocabularies you may have missed and plan a rerun. If your search is under way, we can help document it.

GB890 Unit 3 questions, answered
Which databases suit a DBA search in GB890?
Business databases such as Business Source Complete and ABI/INFORM are the usual base, with a discipline database added for the topic: PsycINFO for behavior and leadership, a public health or safety database for workplace injury, EconLit for markets. The library guide for your program usually lists what you can reach. Choosing by topic rather than habit is what the documentation should make visible.
What is forward citation searching?
Starting from a key study and finding the later work that cites it, using a citation index or a scholarly search engine. It finds research linked through a shared argument instead of shared vocabulary, which is why it often surfaces studies no keyword string reached. Logging it separately, with the anchor studies named and the date traced, keeps the whole search reproducible.
How many included studies does a GB890 search need?
No fixed number. Reviewers look at whether the search could have found the studies that matter and whether its boundaries are stated. Seventeen well-screened studies with a clean flow diagram are more convincing than eighty loosely related ones. If a careful search returns very few studies, the documentation can become part of the evidence for the gap rather than a weakness in it.
Where can I find a free GB890 Unit 3 sample paper?
This page carries a full GB890 Unit 3 search documentation for a supervisor safety project, with search strings, yields by database, a flow of records and stated gaps.
Why search more than one vocabulary?
Different research traditions describe the same practice in different words. Management researchers write about safety leadership and behavior analysts about observation and feedback, so a search in one vocabulary misses the other.
