Supercongruences for a truncated hypergeometric series

The purpose of this note is to obtain some congruences modulo a power of a prime $p$ involving the truncated hypergeometric series $\sum_{k=1}^{p-1} {(x)_k(1-x)_k\over (1)_k^2}\cdot{1\over k^a}$ for $a=1$ and $a=2$. In the last section, the special case $x=1/2$ is considered.
