Photovoice – Evaluation through Photography

A picture’s worth a thousand words, and a method called photovoice takes advantage of pictures’ compelling qualities by incorporating photography into research and evaluation. Photovoice is a participatory evaluation method in which program participants are given cameras to capture images that convey their feelings, beliefs and experiences about an issue. The method is used frequently in advocacy projects, allowing the less powerful stakeholders to communicate about issues that impact their lives.

Photovoice seems to be a particularly popular way to engage youth in projects or in evaluation. For examples of photovoice projects with teenagers, check out the two articles listed at the end of this blog entry. The project described in Necheles et al. used photovoice to engage teenagers in identifying influences over their own health behavior. These teens then developed materials such as posters to advocate for healthier lifestyles among their peers. The article by Strack, Magill and McDonagh presents a project in which teens identified problems in their neighborhoods through photovoice. Both articles provide abundant advice for conducting photovoice projects, including how to engage youth in analyzing photos and ideas for presenting results.

Some photovoice projects carry potential risk for participants. Participants also must be taught how to get and document consent from others who appear in their photos. Consequently, photovoice projects require above-average planning and management. For an excellent resource on managing photovoice projects, check out photovoice.org.

How Many Points on YOUR Rating Scale?

In survey design workshops, we are often asked if rating scales designed to measure respondents’ opinions and attitudes should have an odd number of points, including a neutral mid-point (i.e., “Neither agree or disagree”); or if it’s better to have an even number of points, without a mid-point.  Our answer, which probably frustrates our participants to no end, is “it depends.”  You have to clearly think through what a “neutral” answer means and choose accordingly. Here is a link to a clever blog entry by Jane Davidson that makes this point very well and gives you ways to think about how many points your rating scales should have:

Boxers or briefs? Why having a favorite response scale makes no sense
